Frequency of one of the alleles, A, in a gene pool 6 of 17 q=? Frequency of the other allele, a. 7 of 17 p^2=? The frequency of the homozygote AA 8 of 17 q^2=? The frequency of the homozygote aa 9 of 17 2pq=? The frequency of the heterozygote Aa 10 of 17 Cross fertilisation Fertilisation involving two parents. 11 of 17 Polymorphic Populations where there is more than one alternative for a particular trait 12 of 17 Polymorphism The presence of two or more genotypes, the rarest of which exceeds 1%. 13 of 17 Species A group of individuals of common ancestry that are normally capable of interbreeding to produce fertile offspring 14 of 17 Artificial selection Selective breeding by man 15 of 17 Speciation The formationof a new species that are reproductively isolated from other species 16 of 17 allopatric speciation Speciation that involves initial geographic separation followed by genetic divergence. 17 of 17
