Answer:
Option (a).
Explanation:
Homozygotes individuals has the same genotype whereas the genotype of the heterozygotes are different. The homozygotes may refer the true or pure organism.

Thus, the correct answer is option (a).
Answer:
Polygenic traits
Explanation:
Polygenic traits are traits that are controlled by more than one gene and the physical expression of these genes is significantly influenced by environmental conditions .Characteristics that show continuous variations are controlled by many genes.The genes that control them may be located near each other or even on separate chromosomes. They are often represented as a range of continuous variation because they are not discrete.
