Solved in 2 steps
- If you ignore the effect of crossing over, would you expect differences in the genetic information between a spermatid and the secondary spermatocyte from which it was derived? Explain your answer completely.If you ignore the effect of crossing over, would you expect the genetic information in the two secondary spermatocytes derived from a primary spermatocyte to be identical? Explain your answer completely.True or False: When an individual generates gametes via meiosis the gametes either receive all of their maternal alleles or all of their paternal alleles? b) Explain your answer.
- What event/s during meiosis is simulated by the flipping of the coin? Explain these events briefly.A cell has four pairs of chromosomes. Assuming that crossing over does not occur, what is the probability that a gamete will contain all of the paternal chromosomes? If n equals the number of chromosomes in a set, which of the following expressions can be used to calculate the probability that a gamete will receive all of the paternal chromosomes: (1/2)n, (1/2)n–1, or n1/2?During meiosis in male mammals, sex chromosomes segregate to produce two types of sperm: X‑bearing sperm and Y‑bearing sperm. True or false?
- Although triple-X human females typically have normal offspring, what kinds of gametes, with respect to the X chromosomes, would you expect from such XXX females? Draw meiotic stages that show the gametes that are expected to be produced.A primary spermatocyte has the genotype AaBbee. The A and B loci are linked in cis configuration on the long arm of an acrocentric chromosome. The E locus is on a metacentric chromosome. Show the chromosomes containing these genes at Metaphase I, Telophase I and Telophase II using diagrams. Diagrams must be clearly labelledSuppose you discover two interesting rare cytological abnormalities in the karyotype of a human male. (Akaryotype is the total visible chromosome complement.) There is an extra piece (satellite) on one of the chromosomes of pair 4, and there is an abnormal pattern of staining on one of the chromosomes of pair 7. With the assumption that all the gametes of this male are equally viable, what proportion of his children will have the same karyotype that he has?
- During meiosis, does random assortment occur before or after crossing-over?Describe how meiosis provides for genetic variability.If an animal had a haploid number of two (no sex chromosomes), how many genetically different gametes could it produce? (Assume no crossing over.) What if it had a haploid number of five?Show via a diagram how the product(s) of a meiotic (either I or II) nondisjunction involving the X chromosome of a human female could, when fertilized by a normal male gamete, result in an offspring with Kleinfelter’s syndrome.
