Question 1

testcross

Answer 1

a genetic cross between a homozygous recessive individual and a corresponding suspected heterozygote to determine the genotype of the latter

Question 2

how to find number of gametes produced

Answer 2

2^n; n = number of heterozygotes

Question 3

recombination

Answer 3

a process by which pieces of DNA are broken and recombined to produce new combinations of alleles

Question 4

Recombination frequency

Answer 4

the frequency with which a single chromosomal crossover will take place between two genes during meiosis

Question 5

Independent assortment produces ____ percent recombinants

Answer 5

50

SNP

Answer 14

Single nucleotide polymorphism; single base pair difference in 2 copies of same gene
