Question

multiple-choice question
what are alleles?
different chromosomes
variations of gametes
copies of dna from each parent
variations of genes
rewatch

Explanation:

Alleles are defined as alternative forms (variations) of a single gene that occupy the same position on homologous chromosomes, leading to different traits or expressions. The other options are incorrect: chromosomes are larger structures containing genes, gametes are reproductive cells, and parental DNA copies refer to inherited genetic material broadly, not specifically allele variation.

Answer:

Variations of genes
