suppose that 16 pairs of pintaloosa horses have one offspring per pair. how many of each phenotype would be expected? determine the number out of 16 expected for each phenotype. only count phenotypes for offspring expected to live past one week of age.

Solid: 1 out 16;

Fewspot: 3 out 16;

White Overo: 0

Explanation: A pintaloosa horse is a horse which has genotype LplpOvov, i.e., it is heterozygous for overo and leopard.

Using a Punnett's square, a pair of pintaloosas can produce the following possibilities of offsprings:

Overo genotype

Ov ov

Ov OvOv Ovov

ov Ovov ovov

Leopard genotype

Lp lp

Lp LpLp Lplp

lp Lplp lplp

The expected phenotype for:

Solid is related to the Overo gene and its genotype is ovov, so from the Punnett's square, the possibility for a offspring is 1 out of 16;Fewspot is related to both Overo and Leopard gene. A fewspot horse is both Ovov and LpLp, so the number is 3 out of 16;White Overo is related to the Overo gene and these offspring dies at birth. Since it is asking for the number of ofspring to live past one week of age, there will 0 white overos;
