Each individual inherits one allele of a gene from their mother and one allele from their father. This means that each individual can only have two alleles of a gene, one on each chromosome. However, within a population, there can be multiple alleles of a gene present due to genetic variation and mutations. This genetic diversity allows for different combinations of alleles to be present in different individuals, contributing to the overall genetic variability of a population.

Each gene has a specific location on a chromosome. Different versions of a gene are called alleles. Alleles are alternative forms of a gene that occur at a specific position on a chromosome. Each individual inherits two alleles for each gene, one from each parent.
Throughout a population, there can be many different alleles for a gene. This is because mutations can occur in the DNA sequence of a gene, which can change the function of the gene. Over time, these mutations can accumulate in a population, leading to the development of new alleles.
However, each individual can only have two alleles of a gene. This is because each individual only has two copies of each chromosome. When an individual inherits two different alleles of a gene, they are said to be heterozygous for that gene. When an individual inherits two identical alleles of a gene, they are said to be homozygous for that gene.
The number of alleles that a gene has in a population is called the allele frequency. The allele frequency can vary from population to population. This is because different populations may have different selective pressures that favor different alleles. For example, a population that lives in a cold climate may have a higher frequency of alleles that confer resistance to cold temperatures.
The allele frequency of a gene can also change over time. This is because mutations can occur in the DNA sequence of a gene, which can change the function of the gene. Over time, these mutations can accumulate in a population, leading to the development of new alleles and changes in the allele frequency.
