The alternate form of a gene is called _________.

The alternate form of a gene is called an allele.

Explanation:

Genes are specific sequences of DNA that code for particular traits. For most genes, there can be variations or alternative forms, which are known as alleles. These alleles can result in different expressions of a trait. For example, in humans, the gene for eye color has different alleles, such as those for brown eyes or blue eyes.

Alleles are typically found in pairs in diploid organisms because chromosomes come in pairs—one from each parent. The combination of alleles determines the genotype, and the expression of the trait is the phenotype. Some alleles are dominant, meaning they mask the expression of recessive alleles when both are present.
