Question 1

Hillmer suspected that the baldness gene might be located on this chromosome?

Answer 1

X

Question 2

this type of gene is located close together on the same chromosome

Answer 2

linked genes

Question 3

Nonrecombinant gametes will result in?

Answer 3

original combination of alleles as the parental generation

Question 4

recombinant gametes will result in?

Answer 4

New combination of alleles by crossing over of Parental generations.

Question 5

of recombinant progeny/ total number of progeny x 100% would yield?

Answer 5

recombinant frequency

Question 6

with linked genes and some crossing over, which progeny will predominate?

Answer 6

Non-recombinant

Question 7

wild type alleles are found on one chromosome and mutant alleles are found on the OTHER chromosome

Answer 7

Coupling

Question 8

what is genetic Repulsion?

Answer 8

one chromosome carries a wild allele and a mutant allele and the other carries one wild and one mutant allele.
