Explanation:
Detailed explanation-1: -A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes.
Detailed explanation-2: -If the alleles are different, the individual is heterozygous.
Detailed explanation-3: -Likewise, haploid organisms have single allelic forms, while tetraploids may have as many as four allelic variants in one individual. If an organism possesses the same allelic form of a gene in each of its homologous chromosomes, then it is considered as homozygous for that gene.
