Question

short fur is dominant over long fur. based on the punnett square shown, how many puppies can we expect to have long fur? three one two four

Explanation:

Step1: Analyze the Punnett square

The Punnett square has 4 boxes. Let's assume the dominant allele for short fur is \( S \) and recessive for long fur is \( s \).

Step2: Determine the genotypes

In a typical \( Ss\times Ss \) cross (assuming parents are heterozygous), the genotypes are \( SS:Ss:Ss:ss\). The \( ss \) genotype represents long - fur.

Step3: Count the long - fur genotypes

From the 4 genotypes (\( SS, Ss, Ss, ss \)), only 1 genotype (\( ss \)) has long fur.

Answer:

One
