deleterious homozygotes in a sentence

1. To represent this mathematically, let the relative fitness of deleterious homozygotes and heterozygotes be smaller than that of normal homozygotes " AA " by factors of 1-hs and 1-s respectively, where h is a number between 0 and 1 measuring the degree of dominance ( h = 0 indicates that " A " is completely dominant while h = 1 / 2 indicates no dominance ).
2. It's difficult to find deleterious homozygotes in a sentence.
