Clem is homozygous fir earlobe type what does this mean? a-he has two of the same alleles for earlobe type, one from each parent b-he has two different alleles for earlobe type, one from each parent c-he has one allele for earlobe type from one parent d-he has two alleles for earlobe type, both from the same parent

A- He has two of the same alleles for earlobe type, one from each parent.

He has two of the same alleles for earlobe type, one from each parent.

Explanation:

A person is said to be homozygous if he has two of the same kind of alleles.Further, as per the law of inheritance, an individual inherits one allele each from his/her parents.Therefore, Clem who is homozygous for earlobe type will have two same alleles for the ear lobe and he would have received each of these alleles from one parent each.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
