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
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
