Answer:

So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.

Explanation:

In guinea pigs, for the characteristic<u> hair length, short hair is the dominant allele and long hair is the recessive one</u>.

In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:

P: <u>Ss X Ss </u>

<em>Alleles     S     s </em>

<em>S             SS   Ss </em>

<em>s             Ss    ss </em>

Where the offspring is:

  • <em>50% Ss with short hair phenotype </em>
  • <em>25% SS with short hair phenotype </em>
  • <em>25% ss whose phenotype would be long hair. </em>

According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.
