Detailed explanation-1: -four haploid gametes. A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells? 80.
Detailed explanation-2: -The white shark genome possesses a chromosome number of 2N = 82 and flow cytometry puts the genome size at 6.3 Gbp (7), suggesting a genome size twice that of human.
Detailed explanation-3: -As a result, if the somatic cell has 40 (2n) chromosomes, the haploid gametes will have 20 (n).
Detailed explanation-4: -The haploid cells contain half the number of chromosomes as the diploid cells. Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes.
Detailed explanation-5: -Answer and Explanation: The hypothetical organism’s diploid cell has 40 chromosomes, therefore, the haploid gamete of this organism would be 20 chromosomes.
