Based on this karyotype, what proportion of this women’s gametes would produce viable embryos?
Show via a diagram how the product(s) of a meiotic (either I or II) nondisjunction involving the X chromosome of a human female could, when fertilized by a normal male gamete, result in an offspring with Kleinfelter’s syndrome.
A sexually reproducing animal has two genes that assort independently, one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes is possible in a gamete from this organism?

- 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.arrow_forwardHuman sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?arrow_forwardBriefly describe nondisjunction in meiosis and identify several potential consequences.
