Among dogs, short hair is dominant to long hair and dark coat color is
dominant to white (albino) coat color. Assume that these two coat traits are
caused by independently segregating gene pairs. For each of the crosses given
below, write the most probable genotype (or genotypes if more than one answer
is possible) for the parents. It is important that you select a realistic
symbol set and define each symbol below.
(a) dark, short \(\times\) dark, long \(26 \quad 24 \quad 0\)
(b) albino, short \(\times\) albino, short \(0 \quad 0 \quad 102 \quad 33\)
(c) dark, short \(\times\) albino, short \(16 \quad 0 \quad 16\)
(d) dark, short \(\times\) dark, short \(175 \quad 67 \quad 61 \quad 21\)
Assume that for cross (d), you were interested in determining whether fur
color follows a 3: 1 ratio. Set up (but do not complete the calculations) a
Chi-square test for these data [fur color
in cross (d)].
