Suppose you are analyzing the DNA from the polar bodies formed during human oogenesis. If the woman who produced the oocyte has a mutation in a known disease gene, would analyzing the polar body DNA allow you to infer whether the mutation is present in the mature oocyte? Explain.

A primary oocyte divides to give rise to a secondary oocyte and a first polar body. The secondary oocyte then divides to give rise to an ovum and a second polar body. a. Is the genetic information found in the first polar body identical with that found in the secondary oocyte? Explain your answer. b. Is the genetic information found in the second polar body identical with that in the ovum? Explain your answer.
A company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes. Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?
Which findings support the fact that the presence of the Y- chromosome rather than the lack of a second X-chromosome determines the development of maleness in mammals? A transgenic mouse with two X-chromosomes and the SRY gene from the Y-chromosome develops male sex organs. A human with an XXXY genotype (Klinefelter syndrome) is phenotypically male. A human with an XO genotype (Turner syndrome) is phenotypically female. a and b, but not c a, b, and c
Question:- A) Give one domain.motif found in the SRY portion and state clearly how it leads to the development of the Wollfian system. B) Explain the genotype and the phenotype of an XY female and how such an individual could occur. C) Explain the genotype and the phenotype of an XX male and how such an individual could occur.
How is it that some chromosomal abnormalities are incompatible with life as early as immediately after fertilization, others may lead to spontaneous abortion within the gestation period, while others may lead to babies born but eventually expire?
Removing the patch of tissue called the ZPA from one limb bud and placing into onto another developing limb bud with an intact ZPA results in the digits being duplicated in a mirror image fashion. Which of the following best explains what this revealed regarding the way digit formation is determined? A) The gradient of a gene product emanating from within the ZPA tissue determines digit differentiation, such that low concentrations form the thumb homologue, high concentrations the pinky. B) The ZPA tissue includes all of the genetic blueprints necessary for digit formation, having two ZPAs resulted in twice the gene product, thus two sets of digits, rather than one. C) The ZPA is not responsible for controlling the development of digits. D) None of the above.
When an embryo is homozygous mutant for the gap gene Kr, the fourth and fifth stripes of the pair-rule gene ftz (counting from the anterior end) do not form normally. When the gap gene kni is mutant, the fifth and sixth ftz stripes do not form normally. Explain these results in regard to how segment number is established in the embryo
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.
