Question

If an organism had a haploid number of 300, what would its diploid number be?

Answer 1

If the haploid number of an organism is 300 , then it's diploid number of chromosomes will be 600.

Explanation:

Ploidy is the number of sets of chromosomes in a cell.

Usually a gamete carries a single copy of each chromosome. This is considered as the haploid number (n).
Two gametes unite to form a zygote. Therefore the zygote carries two copies of homozygous chromosomes and is hence diploid (2n).
