onu as ektra aredits (a max of 7.5 extra credits) analyze it and draw simple pictures ( various pieces, and come up answer ext weekend! You need to start studving for exam 1 soon, So, manage your time properly question into smaller pieces. Write down the given information in each piece or a pedigree).Put together whatever you have deduced from the information of with the answer. The best time period to do this assignment is this week, not the . Refer to the p Gene A is locate the pts for the application (usage) of the term "COPY for chromosomes and gee the X chromosome (is X-linked), Answer questions 1 to 6 with regard to this gene. pres of gene A is (are) present in the secondary spermatocytes of Mark in prophase I1? Look over ppts for the gene copies during various stages of a cell cycle. A-One copy only in the X carrying one B- One copy in both of them C- Two copies in both of them BTwo copies only in the X carrying one E- Four copies only in the X carrying one L blc each chnmos6 ms contains 2 cupy or a gene and pnphase z each cl contains rhe half#of CS, onyastngi Mary is Aa, how many copies of gene A would be present in the daughter cells of meiosis I in Mary? A- One copy only in the secondary oocyte 2- If Two copies only in the secondary oocyte C-Two copies in each cell D- Four copies in each cell E-One copy in each cell 3- A crossing over occurred between the two non-sister chromatids of the X chromosomes in Mary's primary oocyte that resumed meiosis this month, and as a result, the A' and 'a' alleles were exchanged. What would be the genotype of the first polar body for gene A, and what is the chance that the ovulated egg cell will carry the 'A allele? (Draw the chromosomes with the corresponding alleles during oogenesis) A- AA, Zero chance B-aa, 100% chance C-Aa, 50% chance D-AA or Aa, 75% chance E-AA or aa, the chance cannot be determined F-Aa or aa, 25% chance G-AAaa, 50% chance Gy 2 copus 4 copus of gert AExplanation / Answer
Answer 1) D. Two copies only in the X carrying one. This is because the prophase contains one copy of the chromosome and one chromosome contains 2 copies/alleles of a single gene.
Answer 2) B. Two copies only in the secondary oocyte. This is because at the end of meiosis, the number of chromosomes is reduced to N (single copy) and one chromosome contains 2 copies/alleles of a single gene.
