9.2 Meiosis And Genetic Variation Flashcards
1
Q
How many cells and how much dna respective to the start does meiosis produce?
A
4 cells
Half the dna
2
Q
Describe meiosis
A
Single chromatids replicate to form a paternal chromosome and a maternal chromosome
This cell splits the maternal and the paternal chromosome up into different cells
The chromosomes in each cell split to form 2 cells with maternal chromatids and 2 cells with paternal chromatids
3
Q
What is a loci?
A
A position of a gene on the chromosome
4
Q
How do different combinations of chromosome happen and what is it called?
A
Chromosomes during mitosis or
meiosis could be either side of the splitting cell
Independent Assortment
5
Q
Describe the process in which chromosomes exchange alleles
A
Chromatids on chromosomes cross and loop over and the genetic info is mixed
