Recombinant Gametes

GENES-OEV2DB

Two true breeding lines of plants are to be used for gene mapping research. Regarding five loci (L, M, P, Q, and R), Line 12 has the genotype LLmmppQQRR, and Line 07 has the genotype llMMPPqqrr. These five loci are located on a single chromosome and are physically arranged in the alphabetical order presented.

These two lines are crossed to produce F1 individuals, and the F1 plants are then self-fertilized to produce F2 individuals.

F1 plants may produce a variety of gametic types.

Indicate which gametes below are recombinant types that are possible from these F1 individuals.

Select ALL that apply.

A

L-M-P-Q-R

B

l-M-P-q-r

C

L-m-p-Q-r

D

L-m-p-Q-R
