Some biology students wanted to determine whether a pair of brown mice purchased at a pet store was homozygous dominant or heterozygous for fur color. They let the mice mate and examined the offspring. Six mice were born. All six had brown fur.

Some of the students felt that this was enough evidence to prove that the mice were homozygous for brown fur color. Other students did not, so another experiment was planned.

Describe the next experiment the students could conduct to determine whether the parent mice are homozygous brown or heterozygous. Explain your answer.

...?

The next experiment the students could conduct is to interbreed the offspring (F1) to produce another generation (F2). The original brown parents were both homozygous for the dominant allele (BB). One or both of the parents was heterozygous if some of the F2 showed the recessive phenotype (bb).

Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.

Mark me brainiest answer is b

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.

Speckled and striped beans (mice) had the best survival rates. Why?

A) They reproduced very rapidly.

B) Coloration was a form of camouflage.

C) They mimicked other mice and were spared.

D) The speckled and striped beans had a wider range.
