Question

in a group of guinea pigs, some individuals have brown eyes and others have red eyes. in this group, the gene for the eye color trait has two alleles. the allele for brown eyes (e) is dominant over the allele for red eyes (e).
complete the punnett square to show all possible genotypes of the offspring from a cross between two guinea pigs.
e e
e i
e
save answer

Explanation:

Step1: Determine the alleles from each parent

One parent has alleles \(E\) and \(e\), and the other parent has alleles \(e\) and \(e\).

Step2: Fill in the Punnett square

• For the first row (parent with \(E\) and \(e\) and parent with \(e\)):
• When \(E\) (from first parent) combines with \(e\) (from second parent): \(Ee\)
• When \(e\) (from first parent) combines with \(e\) (from second parent): \(ee\)
• For the second row (parent with \(e\) and parent with \(e\)):
• When \(e\) (from first parent) combines with \(e\) (from second parent): \(ee\)
• When \(e\) (from first parent) combines with \(e\) (from second parent): \(ee\)

Answer:

	\(E\)	\(e\)
\(e\)	\(ee\)	\(ee\)
