What are almond eyes?
Almond eye shape Almond-shaped eyes have a smaller eyelid and are longer in width than they are round — just like an almond! This eye shape tapers to a point by the tear duct and the outer eye.

What does the term 2pq represent in the Hardy Weinberg principle quizlet?
What do the variables in the Hardy-Weinberg equation represent P P2 q q2 2pq?
The frequency of genotypes in a population can be represented by p2+2pq+q2= 1, with p2 equal to the frequency of the homozygous dominant genotype, 2pq equal to the frequency of the heterozygous genotype, and q2 equal to the frequency of the recessive genotype.
