on, a single chromosome fails to separate. In others, none of the chromosomes separate. Suppose an egg is produced in which none of the chromosomes separate during meiosis II. What is the chromosome number of the zygote that results if this egg is fertilized by a normal sperm?

Answer:

haploid (n) or triploid (3n)

Explanation:

If none of the chromosomes separate during meiosis, the resulting gametes will either lack chromosome or have diploid number (2n) of chromosome instead of a haploid number.

If an egg without chromosome (o) fertilizes a normal sperm (n), the resulting zygote will have haploid number (n) of chromosome.

If an egg with diploid number of chromosome (2n) fertilizes a normal sperm (n), the resulting zygote will be a triploid with 3n number of chromosome.
