alleles are described as _________________.
o alternate versions of a gene
o homologous chromosomes
o environmental factors that affect gene expression
o alternate phenotypes

Explanation:

Alleles are different forms of the same gene. For example, for a gene controlling flower color, there could be an allele for red color and another for white color. Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same genes at the same loci but can have different alleles. Environmental factors affecting gene expression are external influences like temperature or light, not alleles. Alternate phenotypes are the observable traits (like red or white flowers) which are the result of allele combinations, not the alleles themselves.

Answer:

alternate versions of a gene
