Verified step by step guidance1
Understand the concept of haploid and diploid numbers: In sexually reproducing organisms, the diploid number refers to the total number of chromosomes in a somatic cell, while the haploid number is the number of chromosomes in a gamete (sperm or egg cell). The haploid number is half of the diploid number.
Identify the diploid number for domestic cats: Domestic cats (Felis catus) have a diploid number of 38 chromosomes. This means that each somatic cell contains 38 chromosomes.
Calculate the haploid number: Since the haploid number is half of the diploid number, divide the diploid number by 2 to find the haploid number. Use the formula:
Perform the division: Divide 38 by 2 to determine the haploid number of chromosomes in a domestic cat.
Conclude with the haploid number: The result of the division gives you the haploid number, which represents the number of chromosomes in a gamete of a domestic cat.
