Heterozygous alleles are found on ________ chromosomes
Ksju [112]

Answer is Homologous.

A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.  

Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.

Each of the species of finches on the galapagos islands has its own distinctive ________ and ________.
sergiy2304 [10]

Each of the species of finches on the Galapagos Islands has its own distinctive beak and ecological niche.

<h2>Reason :</h2>

Darwin observed that the finches evolved thanks to the difference in their habitat. Consistent environmental differences in several habitats on different islands in the Galapagos, the supply of different foods sources (seeds, cactus, insects, and fruit) promotes directional selection on resident finches for optimal beak morphology which maximizes survival under local conditions.

This process has produced more distinct species of finches, all unique to the archipelago. He noticed that every finch species is having a different type of beak, counting on the food available on its island.
