Q1. Hypophosphatemia (vitamin D-resistant rickets) is inherited as the sex-linked dominant trait. The relevant gene is found on an X chromosome. What is an expected outcome of a cross between a homozygous recessive woman and a man with hypophosphatemia?
Q2. A chimeric gene containing a cloned cDNA of the coat protein (CP) gene of tobacco mosaic virus (TMV) was introduced into tobacco cells on a Ti plasmid of Agrobacterium tumefaciens from which tumour inducing genes had been removed. Plants regenerated from transformed cells expressed TMV mRNA and CP as a nuclear trait. Seedlings from self-fertilized transgenic plants were inoculated with TMV and observed for expansion of disease symptoms. The seedlings that expressed the CP gene were delayed in symptom development and 10 to 60 percent of transgenic plants failed to develop symptoms for the duration of the experiments. Increasing the concentration of TMV in the inoculum shortened the delay in appearance of symptoms. The results of these experiments point to that plants can be genetically transformed for resistance to virus disease development.
He was puzzled, combative, and he refuses to drink any water or any liquid. He lived on Oct. 7th, 1849. While said to the man's name, the student thought "Nevermore!" What was his diagnosis.

The measurements to be comparable in both preparations. Illustrate one experiment you could perform to demonstrate such lack of equivalence of the two cells in the zygote. Noticeably state the expected outcome of your experiment in the reply you prov..
Do you really think the age of the man is main in determining the chance of chromosomal abnormalities? Why or why not with appropriate reasons. Describe a single meiosis event.
Describe how the cell derives additional energy by switching . What was the key factor that determined this change.
Darwin understood how natural selection works in the presence of a population with many variant types. What does that variation consist of? How does variation arise? How does it spread during the population.
In humans, oogenesis in comparison to spermatogenesis is different in that. cytokinesis is unequal during the meiotic divisions.
While Mexican hairless dogs are crossed with normally haired dogs, about half the pups are hairless and half have hair. While, though, two Mexican hairless dogs are mated, about a third of the pups produced hair, about two thirds are hairless and som..
