Nondisjunction which can affect sex chromosomes as well as autosomal chromosomes as a common cause of genetic disorders. Use the space provided to illustrate the process of nondisjunction with the end result being that one cell exhibits in the monopsony me while other one exhibits trisomy.

Analysis of X-Linked Dominant and Recessive Traits A young boy is color-blind. His one brother and five sisters are not. The boy has three maternal uncles and four maternal aunts. None of his uncles children or grandchildren is color-blind. One of the maternal aunts married a color-blind man, and half of her children, both male and female, are color-blind. The other aunts married men who have normal color vision. All their daughters have normal vision, but half of their sons are color-blind. a. Which of the boys four grandparents transmitted the gene for color blindness? b. Are any of the boys aunts or uncles color-blind? c. Is either of the boys parents color-blind?

X-linked inheritance and must use the Punnet square
Mutant female: yellow body and purple eyes. Male: Normal Use: https://www.sciencecourseware.org/FlyLabJS/ Which mutant alleles are dominant? Which mutant alleles are recessive? Which mutant alleles are sex-linked? Which mutant alleles are autosomal? Can you tell at this point if the two genes are linked? Show the results of the dihybrid analysis. Are genes segregating independently? What is the evidence for or against this? Show the crosses you will use to obtain the mapping data. For the mapping crosses, Write out the crossing scheme and make a table of the results (ignore sex in this table, combine the male and female progeny). Identify the parental classes and the recombinant classes. For a 3-point cross, identify the double cross overs. Show your calculations for the recombination frequencies between the three genes (for the 3-point cross) or the two genes (for the two-point crosses). Draw a map of the Drosophila chromosomes 2, 3, and X, including…

Some traits are expressed by both in the male and female humans,but kindly elaborate such traits which are only present in male or in female, give example/s which could be explain under sex-limited and sex-influenced genes.

Familial Down syndrome is similar to primary Down syndrome in that it is caused by trisomy 21. However, in familial Down syndrome, all or part of the third copy of chromosome 21 has translocated onto another autosome, typically chromosome 14. In cases of familial Down syndrome, one of the parents of the affected child is often a carrier of a translocated chromosome. The translocation carrier parent does not have Down syndrome because he or she has a total of two copies of chromosome 21. Suppose that a woman is a translocation carrier of chromosome 21 on chromosome 14. She conceives six zygotes with a normal man who carries no aneuploidies. Match the description of the chromosomes inherited by each zygote with the viability of the zygote. Viable normal, or translocation carrier Viable, with Down syndrome Inviable Answer Bank two normal copies of 21, one normal copy of 14 two normal copies of 21, two normal copies of 14 one 21 to 14 translocation, one normal copy of 21, two normal copies…
