Unformatted text preview: trait may be either the same or the can both be different from each other. If they are the same they are called homozygous and if they are different they are called heterozygous. 2. Some genes are dominate and this can cause heterozygous individuals to express only one allele, the dominate one while showing no signs of the recessive allele. This can cause the phenotype to not always reveal the genotype of an individual. This means that an individual can carry an allele or trait and not show it. 3. Using Mendels law of segregation, the offspring of two heterozygous parents can end up with any combination of alleles. When the gametes combine at fertilization they do not care which alleles they carry. The alleles a person inherits are strictly by chance so the rules of probability can be used to which pairings a person might have. The Punnett square is used illustrate this law....
