What term is used to describe all the alleles at every locus for all individuals within a population?

Answer: GENE POOL is used to describe all the alleles at every locus for all individuals within a population.

Explanation: The gene pool consists of the sum total of all the genes in a particular population. It includes all the genetic information encoded in these genes.

The Hardy-Weinberg law provides equation to relate genotype frequencies and allele frequencies in a randomly mating population;

p² + 2pq + q² = 1 for two alleles such as A and a, where p and q are probabilities of allele frequencies. That is,

p = homozygous dominant

pq = heterozygous

q = homozygous recessive

The gene pool is commonly used during population studies. Therefore, population genetics is the branch of genetics that describes inheritance on the population level in mathematical terms.
