Question

1. base your answers on the diagram below. the diagram shows the offspring of a white mouse and a gray mouse. all of the offspring are gray. parents→ x key g gray (dominant) g white (recessive) offspring→ i. which is the correct gene - combination for the parents shown in the diagram? a gg x gg b gg x gg c gg x gg d gg x gg

Explanation:

Step1: Identify dominant and recessive traits

Gray (G) is dominant, white (g) is recessive.

Step2: Analyze parent phenotypes

One parent is white (must be gg as white is recessive).

Step3: Analyze offspring phenotypes

All offspring are gray. If one parent is gg, the other must be GG to ensure all offspring have at least one G (dominant allele) and are gray.

Answer:

D. gg x GG
