5) The alleles of a gene are found at chromosomes. A) the same locus on nonhomologousB) different loci on homologousC) different loci on nonhomologousD) the same locus on homologous

option D

Explanation:

The alleles of a gene can be described as the variant form of a gene. for example A and a are two alleles coding for the trait tallness. these forms are located at the same position ie locus on a chromosome. thus they are located on the same position for two similar chromosomes (homologous chromosomes).

for the points

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
