Question

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Number of:

Solid:____
Fewspot:_____
White Overo:______

Answer 1

Hello your question is incomplete below is the missing part

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.

Answer :

Number of

solid, fewspots: 1/16

solid, leapord: 2/16

solid, white: 1/16

Fewspots: 2/16

white overo: 2/16

Step-by-step explanation:

Using the given information it can seen that one copy of OV will result in Overo, whereas two copies OVOV offspring will die soon after birth. If 16 pairs of pintaloosa (OVovLPlp) horses are mated and each have one pair of offspring, then it can represented in the table attached below:

from the table we can deduce that :

Number of

solid, fewspots: 1/16

solid, leapord: 2/16

solid, white: 1/16

Fewspots: 2/16

white overo: 2/1
