Verified step by step guidance1
Understand the concept of diploid and haploid chromosome numbers. Diploid refers to the total number of chromosomes in a somatic cell, which is typically double the number found in gametes. Haploid refers to the number of chromosomes in gametes, which is half of the diploid number.
Identify the diploid chromosome number given in the problem, which is 78. This means that the organism's somatic cells contain 78 chromosomes.
To find the number of chromosomes in the gametes, you need to determine the haploid number. Since gametes are haploid, they contain half the number of chromosomes compared to diploid cells.
Calculate the haploid number by dividing the diploid number by 2. Use the formula: .
The result of this division will give you the number of chromosomes present in the gametes, which is the haploid number.
