The question is about a test cross. Definition of a test cross: Generally a cross involving a homozygous recessive individual. When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous, then approximately 50% of the offspring should display the recessive phenotype. If the individual is homozygous all the progeny will have the dominant phenotype. James' suggestion to use show the result of the two possible crosses with a Punnet square is a great suggestion.
Answer:
Adaptation
Explanation:
In this case predation is the selection pressure for natural selection in the mice population. Because the black mice stand out against the brown sand dunes backdrop, they are easily located and predated on by the hawks. Therefore, black mice have a lower chance (compared to brown mice) to reach reproductive age and pass down their genes to the next generation. With subsequent generations, therefore, there will be more and more brown mice in the population.
