A second hit might occur because of loss of heterozygosity. Explain loss of heterozygosity using your own words. Describe a mechanism by which loss of heterozygosity might arise
Step by step
Solved in 3 steps
- What is loss of heterozygosity ?An individual heterozygous for a reciprocal translocation possesses the following chromosomes: A B • C D E F G A B • C D V W X R S • T U E F G R S • T U V W X Q. Give the products that result from alternate, adjacent-1, and adjacent-2 segregation.Explain at the biochemical or enzymatic level, the phenotypic consequencesof alleles incase of following cross. Rr (pink flower) x Rr (pink flower) (progeny are 1 RR (red flower) :2 Rr (pink flower): 1rr(white flower) how alleles contribute to a phenotype through metabolism.
- How to detect a loss of heterozygosity?An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Explain why the fertility of this individual is likely to be less than the fertility of an individual without a translocation.Match the type of change in the number of sets of chromosomes, as shown below, with the process.
- Cystic fibrosis is a genetic disease caused by the lack of a functional membrane transport protein. Formation of the protein requires the dominant allele, C, so CC and Cc = not affected with Cystic fibrosis and cc = Cystic fibrosis. A female heterozygous at the C gene is married to a man homozygous for the Cystic fibrosis allele.Explain the equation E+S---->ES----> E + P.An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw the products of alternate, adjacent-1, and adjacent-2 segregations.
- Why B is correct?Explain how it is possible for a person with a translocationor an inversion to be phenotypically normal.The aldose gene is 10 map units from the fructose gene. (A = dominant allele, can produce aldose; a = recessive allele, cannot produce aldose; F = dominant allele, can produce fructose; f = recessive allele, cannot produce fructose). You cross worms with the chromosomes shown below. What is the probability that offspring will be able to produce only aldose (and not fructose)? A f a f ----- X ----- a F a f A) 10% B) 5% C) 90% D) 45% E) 0% F) 25% G) 50% H) 33%
