Question 1

DNA Recombination

Answer 1

Answer 2

The frequency with which a single chromosomal crossing occurs between two genes during meiosis.

Question 3

Answer 3

depict relative positions of loci based on the degree of recombination

Question 4

Physical Map

Answer 4

Show the actual (physical) distance between loci (in nucleotides)

Question 5

Parental Type

Answer 5

an offspring that has the same phenotype as one or both of its parents

Question 6

Non-parental Type

Answer 6

an offspring that does not have the same phenotype as one or both of its parents

Question 7

Linked

Answer 7

When genes are found on different chromosomes or far apart on the same chromosome, they assort independently.
