1. The biological manigestion of the traits 2. A condition where wherein two identical alleles are present
3. A condition wherein different alleles are present

Answer please

1. phenotype

2. heterozygous

3. homo-zygous

Explanation:

In genetics, phenotype refers to the observable characteristics/ traits in a particular organism. An individual phenotype results from the interaction of genes and the environment. Moreover, in diploid (2n) species, an organism is heterozygous for a given trait when it carries two different gene variants or 'alleles' of the same gene. These two alleles are received from both parents, i.e., one allele from one parent and another one from the other parent. Finally, an organism is homo-zygous for a given trait when it carries two identical alleles of the same gene.
