Two organisms with genotype aabbccddee mate. these loci are all independent. what fraction of the offspring will have the same genotype as the parents?

100%

Explanation:

The given parental genotype is homozygous for all the genes. According to the given information, both the parents are homozygous for five genes and have genotype "aabbccddee". Since both the parents are homozygous for all the loci, meiosis during gamete formation would result in the formation of all same types of gametes from both the parents.

Both the parents will form all the gametes with an "abcde" genetic constitution. The random fusion of gametes with a given genotype will form all the progeny with genotype "aabbccddee". Therefore, the given parents will produce 100% genetically identical progeny to them.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
