Question
Chapter 2, Problem 17P
Summary Introduction
To determine:
The chances for the genotype of zygote obtained after fertilization of a B C D E sperm and a b c D e egg and the genotypes of a sperm or egg that obtain from this fertilization.
Introduction:
Fertilization is the process of fusion of male gamete with female gamete. This produces a new structure called zygote. The process is taken place in the uterine tube of female in humans.

Students have asked these similar questions
A specific human individual with a male sex has the same sex chromosome complement as a metafemale Drosophila fly. Both individuals have a diploid set of autosomes.i) What is the sex chromosome complement of these two individuals? ii) If these individuals were produced from a fertilization event involving an abnormal egg and abnormal sperm cell, provide the genetic make-up of the two gametes? Clearly indicate the male and female gametes.
A male Drosophila melanogaster has the genotype A/a; B/b; C/c; XD/Y (all genes are on separate chromosomes). How many different sperm genotypes can it produce through meiosis of one single pre-gametic (2n) cell? (remember, there is no crossing over in male Drosophila)
Explain.
Butterflies have an X-Y sex-determination system that is different from that of flies or humans. Female butterflies may be either XY or X0, while butterflies with two or more X chromosomes are males. This photograph shows a tiger swallowtail gynandromorph, which is half male (left side) and half female (right side). Given that the first division of the zygote divides the embryo into the future right and left halves of the butterfly, propose a hypothesis that explains how nondisjunction during the first mitosis might have produced this unusual-looking butterfly.
Question is also in the picture.

- A diploid organism produces four gametes from one parent cell through the process of meiosis. Two gametes are found to have 7 chromosomes and two gametes are found to have 5 chromosomes. A) Is this the expected number of chromosomes that would be found in each gamete following a normal cycle of meiosis? If yes, explain why. If no, explain why not and describe how the gamete situation described above occurred.
