The total collection of alleles in a population at any one time makes up that population's ________.a. genotypeb. gene poolc. allele frequencyd. heterozygote frequency
Gene pool. Think of it like this. Humans have tons of genes. Imagine taking just one of those genes between your fingers (if you could - they’re too small in reality) and focusing on just one location or locus of that gene. We would see 2 copies of that gene and each copy is called an allele. If they’re the same, they are homo-zygous. If they are different, they are hetero-zygous. NOW the important part regarding a gene pool. If we took the same gene from a population or large group of humans and identified 20 alleles at that location/locus, then those 20 alleles would make up the gene pool for that locus/location. Take that a little further, and count ALL alleles at ALL locations or loci (plural for locus) and you get the FULL gene pool for the species.
