Question

spongebob is heterozygous yellow(y). susie is pink. what % of their kids are pink?

Explanation:

Step1: Determine the genotypes

SpongeBob is heterozygous yellow, so his genotype is \(Yy\). Susie is pink. Assuming pink is recessive (\(yy\)).

Step2: Set up the Punnett square

	\(Y\)	\(y\)
\(y\)	\(Yy\)	\(yy\)

Step3: Calculate the percentage

Out of 4 possible offspring genotypes (\(Yy, Yy, yy, yy\)), 2 are \(yy\) (pink). So \(\frac{2}{4}= 0.5 = 50\%\)

Answer:

50%
