NEET BIOLOGY

Detailed explanation-1: -Therefore, if the meiocyte of an organism has 24 chromosomes, then the gamete will have 12 chromosomes.

Detailed explanation-2: -If the sperm and egg cells of a butterfly have six chromosomes, 12 chromosomes will be there in the maggot larvae. This is because maggot larvae forms due to the fusion of egg and sperm cells. Since egg contains 6 and sperm cells contains 6 chromosomes, maggot larvae will get both sperm cell and egg cell chromosomes.

Detailed explanation-3: -Assigning genes or genetic elements to chromosomes is an important step when considering how genomes evolved. The monarch butterfly has a reported haploid chromosome number of 30.

Detailed explanation-4: -In metazoan animals, the greatest range of within-genus karyotype variation not related to polyploidy is found in Agrodiaetus blue butterflies, where diploid chromosome number ranges between species from 2n = 20 to 2n = 268 in spite of morphological similarity and very recent time of species divergence [4].

Detailed explanation-5: -Interestingly, in butterflies, it is the female gamete (the egg) that determines the sex of the offspring. In mammals, females have 2 “X” chromosomes and males have an “X” and a “Y” chromosome. If an egg is fertilized by a sperm carrying an X chromosome, it becomes a female (XX).
