Question

Two true-breeding guinea pigs were crossed. One had short, black fur, and the other had long, brown fur. Fur length is carried on one gene and fur color on another. Select all offspring phenotypes that you would expect in later generations if…

. . . the genes are nearby on the same chromosome.

short, black fur

long, black fur

short, brown fur

long, brown fur

Answer 1

Main expectation: mostly the parental phenotypes — short, black and long, brown.

Because the two genes are nearby (linked), recombination is rare, so the recombinant phenotypes (long, black and short, brown) can appear only at low frequency (and would be absent if there were complete/no crossing‑over).
