Question

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

Explanation:

Step1: Determine the genotypes

Let \( S \) represent the allele for short fur (dominant) and \( s \) represent the allele for long fur (recessive). The Punnett square is likely for a cross between two heterozygous parents (\( Ss\times Ss \)).

Step2: Analyze the Punnett square

The Punnett square for \( Ss\times Ss \) gives the following genotypes: \( SS:Ss:Ss:ss = 1:2:2:1 \). The genotype \( ss \) results in long - fur puppies.

Step3: Count the number of long - fur genotypes

From the Punnett square analysis, there is \( 1 \) \( ss \) genotype out of \( 4 \) total genotypes in a typical \( 2\times2 \) Punnett square (assuming the given Punnett square is for a monohybrid cross of two heterozygotes).
