- How Is Sex Determined? The absence of a Y chromosome in an early embryo causes the: a. embryonic testis to become an ovary b. Wolffian duct system to develop c. Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testisMutations Can Uncouple Chromosomal Sex from Phenotypic Sex Give an example of a situation in which genetic sex, gonadal sex, and phenotypic sex do not coincide. Explain why they do not coincide.▷ An oocyte is: O haploid O diploid O not enough info to tell
- Suppose that a heterozygous female mates with a heterozygous male. What is the probability that a child produced from this union will develop Parkinson disease-14?please show punnett square alsoYour friend is pregnant with triplets. She thinks that itis equally likely that she will be the mother of 3 sons,3 daughters, 2 sons and 1 daughter, or 1 son and 2daughters. Is she correct? Explain. (Assume that eachof the triplets is from a separate fertilization, and thatboys and girls are equally likely.)About sexual reproduction: Involves one parent where a new individual develops being an exact copy of the parent also known as clone and no gamete or reproductive organ is involved O Only the mother contributes with the oocyte or egg where a new individual is formed with an exact copy of the mother's genes O Involves two parents, where each parent contributes with special germ cells or gametes that once united in fertilization, a new individual develops receiving genetic material from both parents and the product of gene recombination O Involves the father only which contributes with special germ cells or spermatozoa that once fertilized, a new individual develops receiving genetic material from the father and the product of gene recombination Next » « Previous

But, I am wondering how do you determine it is half of the son and none daughterBased on this karyotype, what proportion of this women's gametes (i.e., eggs) would produce viable embryo's? By viable I mean normal phenotype where the baby can survive without any genetic disease.Males are Homozygous Heterozygous Hemizygous None of the above
