🐏 The Hardy-Weinberg Principle (AQA)


In the wild, each species may exist as one population or multiple populations. Different populations correspond to defined areas – habitats.


The sum of all present alleles for a given gene in a given population is known as the gene pool.


This is essentially a way of thinking about all the individuals in a population contributing their alleles towards the overall allele frequency.



How could we keep track of the frequency of each allele for a given trait when we have a dominant-recessive interaction? More specifically, how could we account for the visible dominant traits as homozygous or heterozygous, since both look…
