Document Summary

Does the dominance status of an allele affect its frequency in a population. Q: if we start with a common dominant allele and a rare recessive allele, with no selection, what will happen. A: the frequencies of the alleles do not change. If all genotypes are equally fit, an allele"s dominance status does not affect it"s frequency. All of mendel"s principles still apply when we are talking about a population. But when we look at populations genetics they don"t usually show classic. But, as in mendelian genetics if we know the allele frequencies (parental genotypes) we can predict distribution of offspring genotypes. In a randomly mated population we can use allele frequencies to calculate expected genotypes frequencies. In populations genetics, we are usually working with less round numbers. Then genotype frequencies are predictable from allele frequencies. Hardy-weinberg equilibrium is what no evolution looks like.
