Follow-up Question
Thank you for the follow-up! So, in what sort of conditions would there be an extra Y chromosome? If it's not there in the first place.. how can it get transversed/moved to another chromosome? Unless it is duplicated?

- Why are the X and Y chromosomes not considered homologous even though they recombine at the PAR region?arrow_forwardLet's suppose that a normal chromosome carries genes labeled A through /. The centromere is located between genes B and C. As shown below, a chromosome with an inversion has a region where the order of certain genes is reversed. Note: The genes on the inverted chromosome carry recessive alleles that are designated with lowercase letters. Normal chromosome: A B Centromere C D E F G H I Chromosome with an inversion: a b Centromere c d h g fei A. If you ignore possible fertility issues, do you think this individual will otherwise be phenotypically normal or abnormal? Explain why. B. Let's suppose a single crossover during meiosis occurs between these two homologs in the region between genes F and G (and between g and f). Following the crossover, what is the order of genes (designated with upper and lower case letters) on the two resulting chromosomes. Include centromeres in your answer. Hint: Both of the resulting chromosomes will carry gene deletions and gene duplications.arrow_forwardWhat is the probability of fixation of a unique new, neutralmutation in a population of N haploid individuals?arrow_forward
- What is pleiotropy in biology?arrow_forwardA 45-year-old man with HIV infection comes to the office because of a 6-week history of swelling near the left side of his neck. His most recent CD4+ T-lymphocyte count was 42/mm3 (N>500), and plasma HIV viral load was 55,000 copies/mL. He currently takes no medications. His temperature is 38oC (100oF), pulse is 72/min, respirations are 12/min and blood pressure is 120/81 mmHg. Physical examination shows a left supraclavicular mass. Immunohistochemical staining of a biopsy specimen of the mass confirms the presence of the causal virus’s DNA and replication within lymphoma cells but not in nearby normal cells. Which of the following is the most likely explanation for the tumor formation? a) Chronic immune activation of B lymphocytes b) Chronic immune activation of T lymphocytes c) Inhibition of B-lymphocyte tumor surveillance d) Inhibition of T-lymphocyte tumor surveillance e) Malignant transformation of B lymphocytes f) Malignant transformation of T lymphocytesarrow_forwardRecombination frequencies have been determined between four genes (A, B, C and D) as follows: A-B: 20%, B-C: 50%, A-D: 50%, C-D: 5% Which of the four genes is/are likely linked on the same chromosome?arrow_forward
