Because they were all brought up in different environments
A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.
- Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
- When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
- When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
- When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.
Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

48 chromosomes, 48, XY in the male and 48, XX in the female gorilla :)
This observation may indicate that the patella is responding when its reflexes are tested and that those responses are being strengthened by other parts of the spinal cord that are not usual, indicating diversion. The patellar reflex indicates that there is activity in the L<span>2, L3, and L4 segments of the </span><span>spinal cord.</span>
