. Each group of questions below concerns an experimental or a labo tory situation. In each case, first study
the description of the situation. Then choose the one best answer to each que on following it.
In dogs, one pair of alleles determines coat color (dark and albino). Another pair of alleles determines hair length (short
and long). Thus, each gamete will contain one of the coat-color alleles, Cor cand one of the hair-length alleles, Bor b. In
repeated crosses of a specific dark, short-haired dog with an albino, long-haired dog, all the offspring were dark with
short hair, as shown in cross I. However, in subsequent crosses of another dark, short-haired dog with a dark, long-
haired dog, the ratios shown in cross Il below were obtained.
Cross Parents
I. Dark, short hair x Albino, long hair
II. Dark, short hair x Dark, long hair
Offspring
All dark, short hair
3 dark, short hair
3 dark, long hair
1 albino, short hair
1 albino, long hair
In cross II, the genotype of the dark, short-haired parent is
