Each set of genes is an independent event. Each probability of aa, bb, etc. is 1/4. So the probability of aabbccddee is (1/4)5 = 1/1024
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
Homozygous.
The genes an organism contains is called the organism's genotype.
An organism with the alleles BB would be homozygous dominant.

homozygous recessive
Gregor Mendel devised the fundamental tool of the test cross. It is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype .
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.

An organism with the alleles BB would be homozygous dominant.
homozygous recessive
It depends on the trait. A dominate trait is not always an advantage, and a recessive trait is not always at a disadvantage.
The term used to refer to an organism that has two indentical alleles for the particular trait is homozygous. A trait could be homozygous dominant (TT), homozygous recessive (tt), or homozygous for incomplete dominance (rr).
