Can you find the amount of heterozygotes in a pop. from the phenotypes shown in the pop [duplicate]

I know the hardy Weinberg equation but that is for the amount of alleles not the amount of phenotypes. So if there are 600 black(dominant) organisms in the population and 400 green(recessive) ...

Easy Hardy Weinberg Equilibrium [duplicate]

Hi My friend and I get 2 different answers to this question. I would like to know how to calculate the value of q. My friend says that 500/1500=q because there are 500 recessive alleles in the ...

Finding genotype/allele frequencies of second generation in Hardy-Weinberg equilibrium given that the recessive allele is deleterious [duplicate]

A population in Hardy-Weinberg equilibrium has p=0.6 and q=0.4, and allele q (recessive) is deleterious. If 25% of heterozygous individuals and 50% of homozygous recessive individuals die before ...

how can a recessive allele become represented in a significant number of individuals in a population

Darwin believed that individuals that are poorly adapted to their environment are less likely to survive and reproduce. This means that their genes are less likely to be passed to the next generation. ...
