Question
In fruit flies, chromosomal crossing over does not occur in meiosis in males, whereas crossing over does occur in meiosis in females. In fruit flies that are heterozygous at many genes (i.e. many maternal and paternal versions of the genes differ), at what stage would cells no longer be heterozygous for any gene during the process of meiosis?
a)After the second meiotic division in males, and after the first meiotic division in females.
b)After the second meiotic division in both males and females.
c)After the first meiotic division in both males and females.
d)After the first meiotic division in males, and after the second meiotic division in females.

- Compare meiotic anaphase I with meiotic anaphase II. Which meiotic anaphase is most similar to the mitotic anaphase?arrow_forwardHuman sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?arrow_forwardDuring metaphase I of meiosis, tetrads align along the metaphase plate independently of each other. Therefore, there is a random “shuffle” of maternal and paternal chromosomes in the resulting gametes.The following diagram demonstrates how this works in a diploid cell with four chromosomes . Because there are two pairs of chromosomes and each pair can align in one of two ways during metaphase I, the number of possible variations in the gametes produced is , or .For an organism that is , there are three pairs of chromosomes, so the number of possible variations in the gametes produced due to independent assortment in metaphase I is , or . In an organism with a haploid number of , how many possible combinations of maternal and paternal chromosomes can occur in its gametes? Select one: a. 72=49 b. 27=128 c.17=1 d. 214=16 384arrow_forward
- A diploid organism produces four gametes from one parent cell through the process of meiosis. Two gametes are found to have 7 chromosomes and two gametes are found to have 5 chromosomes. A) Is this the expected number of chromosomes that would be found in each gamete following a normal cycle of meiosis? If yes, explain why. If no, explain why not and describe how the gamete situation described above occurred. B) Determine the number of homologous chromosome pairs that the original parent cell contained, before meiosis began. Explain how you determined this value.arrow_forwardIn kangaroos, the somatic cells are diploid, having 22 chromosomes. How many chromosomes are present in each cell at metaphase II of meiosis?arrow_forwardIf the amount (mass) of DNA in a diploid cell during G1 phase prior to meiosis I is 8 pg (picograms), how much DNA would be present in a daughter cell immediately following: A) meiosis I? B) meiosis II? (for your information, this cell will function as a gamete) HINT: Go through the process of meiosis one step at a time. DNA replication would double the amount of DNA in the cell, cell division divides the DNA into two daughter cells.arrow_forward
- Meiosis is characterized by the pairing of homologouschromosomes during prophase I. In many species, an elaboratestructure called the synaptonemal complex forms betweenhomologues. During this pairing, homologues may exchangechromosomal material at sites called chiasmata. In meiosis I, thehomologues separate from each other, reducing the chromosomenumber to the haploid state (thus the reductive division). It isfollowed by a second division without replication, during whichsister chromatids become separated. The result of meiosis I and IIis four haploid cells. If sister chromatids separated at the first division, would meiosis still work?arrow_forward1) The daughter cells that result from Meiosis 1 are already haploid and unique a) Which even of Meiosis 1 results in the creation of Haploid cells? That is, why are momologous pairs of chromosomes absent in Meiosis 1 daughter cells? 2) The daughter cells are Haploid/Diploid (chose 1) because homologous pairs Are/Are Not ( chose 1) present in the same cell. The chromosomes in each daughter cells are Duplicate/Unduplicated (chose one) Please be briefarrow_forwardA.) In which parent did nondisjunction take place? B.) How many Chromosomes would be in zygote 1, 2, and 3? C.) Which zygote, if any, would be most likely to be healthy? Explain. D.) Name the conditions the non-healthy zygotes have.arrow_forward
- Consider the following two meiocytes in metaphase I, with crossover positions as indicated for cell A. Solid black lines indicate spindle microtubules. Assume blue chromosomes represents paternal chromosomes and green maternal chromosomes. G N D t d Cell A Cell B i) How many chromosomes and chromatids were present in cell A during the G1 phase? Please clearly specify chromosomes and chromatids in your answer. ii) For cell A, list all the gametes that will be produced from this cell. Give the alleles of each gamete contained within a set of brackets. You may ignore independent assortment. iii) For cell B, list all the gametes that will be produced from this cell given crossing over. Give the alleles of each gamete contained within a set of brackets. You may assume that no crossing over would take place.arrow_forwardimagine a giraffe whose diploid is 30. A)Under what circumstances would the giraffe go through a process of meiosis? . b) what will be the final result of this meiosis for the giraffe (# of cells + # of chromosomes/cells)arrow_forwardA diploid (2n) trihybrid individual with the genotype EeFfGg can make eight genetically different gametes. Loci E/e and F/f are on chromosome 1 and locus G/g is on chromosome 2. Explain how a gamete containing the alleles e, f and g may be produced by meiosis. Refer specifically to meiotic events occurring during Prophase I, Metaphase I, Anaphase I and Anaphase II. (NB: remember to refer to the organism above).arrow_forward
