Chapter 5

Question 1

What is the ratio of recombinant to non-recombinant progeny when two genes assort independently

Answer 1

When two genes assort independently, recombinant progeny and nonrecombinant progeny are produced in equal proportions.

Question 2

What is the ratio of recombinant to non-recombinant progeny when two genes are linked with some crossing over

Answer 2

When two genes are linked with some crossing over between them, more nonrecombinant progeny than recombinant progeny are produced.

Question 3

How is recombination frequency calculated

Answer 3

Recombination frequency is calculated by summing the number of recombinant progeny, dividing by the total number of progeny produced in the cross, and multiplying by 100%.

Question 4

What’s the coupling conformation

Answer 4

one chromosome contains both wild-type alleles, one chromosome contains both mutant alleles

Question 5

What’s the repulsion conformation

Answer 5

wild-type allele and mutant allele are found on the same chromosome

Question 6

What does the term recombination mean?

Answer 6

Recombination means that meiosis generates gametes with allelic combinations that differ from the original gametes inherited by the organism.

Question 7

What are two causes of recombination?

Answer 7

1. independent assortment of loci on different chromosomes

2. physical crossing over between two loci on the same chromosome

Question 8

link
