Explanation:
Detailed explanation-1: -Gametes are formed through a process called meiosis, which results in cells with half the number of chromosomes as the original somatic cell. So, if a somatic cell in a butterfly contains 24 chromosomes, a butterfly egg would contain half that number, which is 12 chromosomes.
Detailed explanation-2: -Therefore, if the meiocyte of an organism has 24 chromosomes, then the gamete will have 12 chromosomes.
Detailed explanation-3: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
