Mitosis And Meiosis Flashcards
What are the stages of interphase
G1, synthesis, g2
What is the function of mitosis
To make a genetically identical cell
When does dna replicate
Synthesis interphase
Stages of meiosis
Interphase, prophase, metaphase, anaphase, telophase
How are the sister chromatids of a chromosome similar
They are identical
What are sex cells called
Gametes
What is the importance of meiosis
To produce sex cells to produce 4 genetically unique cells
How many cells are produced by meiosis
4
Where are the alleles Hh found within an organism’s cell
On a chromosome
When do homologous chromosomes separate during meiosis
anaphase I
What are One pair of two chromosomes, on from each parent, that carries genes for a specific trait at the same location
Homologous chromosomes
When does DNA replicate
Synthesis, interphase
When does crossing over occur
Prophase 1
What is “Cell division during which sister chromatids fail to separate properly”
Nondisjunction
If there are 120 chromosomes in a radish cell, how many chromosomes would a radish’s egg cell have
60
A human liver cell in prophase two of meiosis contains 23 chromosomes, how many chromatids does it contain.
46
How many chromosomes would a cell have during metaphase one of meiosis if it has 24 chromosomes during interface?
24 during at the end 12
Sister chromatids separate during what phase of meiosis
Anaphase II
How are The homologous chromosomes similar to one another and how are they different
Similar:
Process by which haploid gametes combine forming a diploid cell with 2n chromosomes with and chromosomes from the female Parent and N chromosomes from the male parent
Fertilization
What is a diploid cell
Two sets of chromosomes
What is a haploid cell
One set of chromosomes a haploid cell is a gamete
Autosome cels
Not a sex chromosomes
Somatic cells
“ a mutation in a body cell”
