Question 2

gametes

Answer 2

unfertilized reproductive cell (egg or sperm)

they are haploid cells (only 23 chromosomes)

Question 3

segregation

Answer 3

the independent separation of alleles on different chromosomes (one allele for one gamete)

Question 4

independent assortment

Answer 4

homologous pairs line up in a random order in metaphase 1

Question 5

crossing over

Answer 5

is the exchange of alleles between homologous pairs (can separate linked genes) parts of non sister chromosomes can cross over, break and rejoin.

Question 6

zygote

Answer 6

a fertilized egg

Question 7

recombination

Answer 7

Chromosomes created when crossing over combines the DNA from two parents into a single chromosome.

Question 8

linked genes

Answer 8

two genes that are located on the same chromosome and tend to be inherited together
