how many cellular divisions in mitosis
1
how many cellular divisions in meiosis
2
how many daughter cells are formed in mitosis
2
how many daughter cells are formed in meiosis
4
only contains one copy of each chromosome
haploid
pairs of chromosomes, one from each parent, that are genetically similar but not identical
homologues
doubled chromosomes pair to form tetrads
meiosis
homologues are separated in
meiosis
in humans, it results in the daughter cells with 23 chromosomes
meiosis
results in formation of sperm and egg
meiosis
the way sex cells are formed
meiosis
separates chromatids into opposite poles of the cell
meiosis 2
in humans, it results in daughter cells with 46 chromosomes
mitosis
results in formation of body or somatic cells
mitosis
when zygote will divide to produce all the cells of the new organism
mitosis
daughter cells compare to each other in what way
mitosis (identical) meiosis (unique)
chromosomes move to cell equator
mitosis and meiosis
occurs in animals and flowering plants
mitosis and meiosis
replication of chromosomes occurs before this process
mitosis and meiosis
in what phase of meiosis do tetrads form
prophase 1
animals and flowering plants have paired chromosomes
true
in diploid organisms, "n" is equal to the number of homologous pairs
true
all of the body cells of an organism have a different number of chromosomes
false
a sex cell, are different in in their chromosomal number
gametes
contains these 2 copies of each chromosome
diploid
break off and attach to adjacent chromatids on the homologous chromosome
during crossing over, portions of chromatids
human body cells have 46 pairs of chromosomes
false
meiosis occurs in all body cells
false
the diploid number of human cells is 23
false
the number of chromosomes in an organism changes from generation to generation
false
when male and female sex cells fuse together
zygote
