Basic Principles of Eukaryotic Gene Mapping

GENES-GSJ1$G

Select ALL that apply.

Key concepts of basic eukaryotic chromosome mapping include

A

two genes close together on the same chromosome pair do not assort independently at meiosis.

B

the occurrence of a crossover can influence the occurrence of a second crossover in an adjacent region.

C

a pair of heterologous chromosomes can exchange segments by crossing-over.

D

gene loci on a chromosome can be mapped by measuring the frequencies of recombinants produced by crossing-over.

E

recombination results from either independent assortment or crossing-over.

F

recombination produces genotypes with exclusively paternal alleles.
