- Discuss how PCR may be used for the detection of disease-causing pathogens in a population during the COVID Pandemic.
Two genes ‘d’ and ‘t’ are assumed to show linkage as well as produce recombinants upto 30%. If dd/ dd individual is crossed with one which is tt/tt. What genotype will produce in first filial generation? Also give the possible meiotic products produced by first generation. If a test cross is performed what phenotypes and genotypes will produced in progeny.

- n fruit flies, normal wings (wild-type) are dominant to vestigial (small, limited functioning) wings. If a true-breeding wild-type male mates with a pure-bred vestigial winged female, what is the probability that any individual offspring will have vestigial wings?
Mendel said that tall are dominant over short plant and green pea pods are dominant over yellow pea pods. A short plant that is hetrozygous for green pea pods is crossed with a hetrozygous plant with both traits. What is the genotype for both parents plant?
