Music producing cells that have_do usual number from chromosomes

Half

wear a pair of chromosomes called one comes from mom and one comes from dad

Homologize

sister come to their pulled apart

Interface to meiosis two

homologous chromosomes are assigned a_

Jean

in humans and X and Y indicate a

Mail

two chromosomes want to hear it from other one inherited from father - same links and general appearance

Molitas chromosome

haploid cells during meiosis and the female of many species; the cells have a little more than DNA and are usually disintegrated

Poor body

how the homologous pairs of chromosomes line up on the metaphase plate

Random or independent assortment

meiosis two anaface to

The chromatids pull apart and move to opposite ends of the cell. They are pulled by the spindle fibers just like mitosis

what does meiosis involves

The division of nuclear contents to make diploid cells into haploid cells

meiosis to tell face too and cytokinesis

The nuclear membrane reforms around the separate chromosomes. The cells divide creating for new cells

The two sex chromosomes that humans have our_and_

X and Y

in an egg the sex comes on is always in_chromosomes in a sperm this chromosomes can be there in_or_

X, X, Y,

chromosomes that contain genes that code for a trait that are not directly related to the sex of an organisms humans have 22 pairs

autosomes

pears one through 22 chromosomes that contain genes for characteristics not directly related to the sex of organisms

autosomes

chromosomes 1 through 22 are called_they contain genes for characteristics that are not related to the_of an organism

autosomes, sex

why can't a gamete have two genes for a particular trait

because they separate in meiosis

cells in your kidney spleen stomach and eyeball are made of_this DNA is not pass on to your children

body cells

to compare mitosis and meiosis remember that mitosis occurs in _cells and create _ that are_to the parents so

body, daughteridentical

haploid mean the cell only has one copy of each_

chromosome

body cells in sex cells have different numbers of blank

chromosomes

each species has its own distinct number of blank

chromosomes

meiosis one: prophase one

chromosomes condense and create sister chromatids nuclear envelope disappears similar chromosomes pair with one another forming homologize chromosome pairs magus chromosomes exchange genetic info by crossing over

meiosis two metaphase two

chromosomes line up in the middle of the cell just like they do in mitosis

Exchange of genetic material between homologous pairs of chromosomes it is a big contribute to genetic variation

crossing over

what is mitosis used for

development, growth, repair

refers to sell that has two copies of each chromosome one from mom's eggs and one from dad sperm somatic cells

diploid

cell has two copies of each chromosome one from other one from dad 44 autosomes

diploid cell

meiosis to ProFace to

each new cell has one chromosome from each mulligans pair. The chromosomes do not duplicate again. Spindle fibers form and stretched across the cell

has one of the chromosomes from each_pair

egg and sperm, homologous

gametes are called_in females and_in males

egg, sperm

inhuman two exes chromosomes indicate a

female

when the egg and sperm come together it is called

fertilize Asian

result of meiosis

four eggs or sperm

our sex sells sperm and egg have DNA that can be passed to offspring

gametes

sex cells: half the number of chromosomes body cells have. Over Oregon females. Sperm in males haploid 23 in

gametes

sexual reproduction involves the joining of two_that result in offspring that are genetically mixture of both parents

gametes

The result of mixing of the genes do the processes of crossing over an independent assortment The result of offspring show new combinations of traits inherited from both parent

genetic recombination

develop into gametes located in ovary in testes

germ cell

term that refers to a cell that has one copy of each chromosome sex cells

haploid

meiosis is this division of the nucleus and take a diploid cell and turn it into a_

haploid cell

so has one copy of each chromosome each egg or sperm has 22 autosomes and one sex chromosome (X, Y) haploid number is 23

haploid cell

The cell has two copies of each chromosome one from the mother and one from the father

haploid, in

A change in the number of chromosomes in an organism

harmful

result of meiosis one

homologies chromosomes are separated from each other

where the chromosomes in each pair called

homologous chromosomes

meiosis one and anaphase one

homologous chromosomes separate from their partners in move to opposite ends of the cell chromatids do not separate here

in mitosis parent and daughter cells are_meaning they have_chromosomes

identical, same

separate sister chromatids remain attached

in phase 1 of meiosis one

resting. After me oh sis one and cytokinesis and before prophase two of meiosis two begins

interkinases

meiosis is sometimes referred to as a reduction division because:

it divides the number of chromosomes

homologous chromosomes have the same_and general appearance

length

how are sperm and egg cells created

meiosis

produces genetically unique cells. Result: haploid cells. Takes place only at certain times in organisms life cycle. Involved in sexual reproduction.

meiosis

what does gameteogenesis involve

meiosis as an initial process in other maturational changes to produce gametes like eggs and sperm

germ cells in your reproductive organs undergo the process of blank to form_

meiosis gametes

result of meiosis one and two

meiosis produces for new cells have formed from the original single cell. Each cell has half the number of chromosomes are present in the original cell

spindle fibers align

metaphase one meiosis one

spindle fibers align

metaphase two meiosis two

produces genetically identical cells. Results and diploid cells. Takes place through organisms and lifetime. Involved in sexual reproduction.

mitosis

meiosis one televise one and cytokinesis

nuclear membrane reforms paired chromosomes are still joint cell divides through cytokinesis

The nuclei of the egg and sperm Cell fuse when fertilization occurs in to form one

nucleus

germ cells are in your reproductive organs and they develop into gametes

ovaries and testes

meiosis one metaphase one

paired Magus chromosomes line up at the middle of the cell pairs of chromosomes line up not the individual chromosomes they don't wind up like this in mitosis

Century so move to opposite sides of cell

proFace to meiosis two

divided into two parts that each contain four phases

process of. meiosis

what is meiosis used for

produce gametes

nuclear membrane breaks down center so moved to poles

prophase one meiosis one

Control development of sex come characteristics two very different sex chromosomes capital X and Y(how sex is determined)

sex chromosome

The Y chromosome is the blank chromosome and carries the_jeans

sex chromosome, mail

directly control the development of sexual characteristics

sex chromosomes

chromosomes that directly controlled the development of sexual characteristics of an organism humans have one pair

sex chromosomesm

Parent cells are known as and only have blank chromosomes

sex sells 23 chromosomes

differ from other human body cells. Body cells have_chromosomes_pairs

sex sells 4623

duplicated chromosomes that remain attached by centromere

sister chromatidsI

body cells are also called

somatic cells

body cells, body tissue, organs, DNA isn't price down to children diploid, 46 chromosomes

somatic cells

The process of homologous chromosomes finding each other and pairing up

synapsis

spindle fiber disassemble

telophase one meiosis o

nuclear membranes form again spindle fibers break apart

telophase two meiosis two

and my guess is the DNA is still copy but the cell divides_

twice

when the egg and sperm together come together the total number of chromosomes should equal_so each only has_chromosomes one from each_pair

two, one, Homologous

Wise important that sex is a haploid

undergo more processing in the ovaries or testes

meiosis one: interphase

yarn like form make an identical copy of itself cell enlargers and prepares to divide

One egg and sperm connect

zygote
