- Explain on how TYR has considerable variety among vastly different species, but can also be extremely similar for closely related species. Also explain how with unlimited resources, we could sample our own data and compare healthy TYR genes with those that have mutations directly. Finally, explain on how the TYR gene plays a crucial role in the melanin biosynthesis process in organisms.arrow_forwardMapping a new mutation on the same chromosome as the mapping genes: Scenario 1 1. If the m mutation is in a gene on the same chromosome as a and b, as shown here, what would be the expected genotype(s) and phenotypes of the F1 individuals? m+b +a+ + m++ +ab Scenario 1: emk 2. If individuals from this F1 generation self-fertilize, what genotypes and phenotypes of progeny would you expect in the F2 generation? Assume that the m, a, and b genes are all linked but you don't need to calculate exact frequencies of each genotype/phenotype. Parental gametes will be m++ or +ab Recombinant metes will be m+b or +a+ if there is a crossover between a and b Or mab and +++ if there is a crossover between m and a The most common categories will be combinations with the parental gametes +a+ wild-type m+b M-only +ab wild-type m++ M-only mab M-only +++ wild-type +a+ +a+ A-only m+b B-only +ab AB m++ wild-type mab AB +++ wild-type +a+ wild-type m+b MB mab MB +++ wild-type A-only m+b wild-type mab A-only…arrow_forward. Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.

- The mitochondrial genome of Chlamydomonas contains the lowest number of genes, 12, of all the species of green algae. However, only 7 proteins are produced inside these mitochondria. Which of the following statements is the best explanation for why only 7 proteins are made from the 12 genes In Chlamydomonas mitochondria? OA Five of the genes are redundant; another copy is expressed from the nuclear genome.. OB. Five of the genes are nonfunctional "pseudogenes". OC Five of the genes are transcribed, but not translated. OD. Five of the genes are coding for proteins that are translated in the cytoplasm.
