Answer:

True

Explanation:

The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.

Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells.

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms. During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

Answer:

1. are heterozygous for the disease.

Explanation:

Since the disease causes the death of chicks before hatching, it means that those with the disease cannot be found in the population. In order for the allele of the disease to be passed from generation to generation, there must be parent birds that are carrying the disease in heterozygous state.
