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.

    Because we are looking a one characteristic, the students should let the offspring mate (F1 generation). If the offspring, are all 100% brown ,then we can conclude that brown fur color is dominant. But if any of the progeny in the F2 generation display a different fur coat color, then we can conclude that one of the parents was carrying a recessive allele, indicating a heterozygous. This explanation is stems from Mendel's Principle of Independent Segregation.

    luk we can, in the first generation we saw all are having brown fur means towo probabilites that it might BB or Bb so we will mate it with hetrozygous mice then if any of the spring got different colour we can say the mice they took from the store is heterozygous but if all again are of brown furs means the mice is gomozygous containing dominant gene BB which is took by them

    We can determine mating this with mice having recessive homozygous fur colour ie. white. It will produce two types progeny in equal proportion.
