- Discuss Concepts One of the human chromosome pairs carries a gene that influences eye color. In an individual human, one chromosome of this pair has an allele of this gene that contributes to the formation of blue eyes. The other chromosome of the pair has an allele that contributes to brown eye color (other genes also influence eye color in humans). After meiosis in the cells of this individual, what fraction of the nuclei will carry the allele that contributes to blue eyes? To brown eyes?arrow_forwardCan you help?arrow_forwardWhich is true about crossing over?arrow_forward
- VISUALIZE Sketch a series of diagrams showing each of the following, making sure to end each series with haploid cells: (a)How a pair of alleles for a single locus segregate in meiosis (b)How the alleles of two unlinked loci assort independently in meiosis (c)How the alleles of two linked loci undergo genetic recombinationarrow_forwardWhich of the following is least likely to produce genetic variation in the offspring of an individual? (a) a DNA replication error caused by DNA polymerase in a body cell of the individual (b) a cross over event during meiosis that creates a new combination of alleles in the gametes (c) independent assortment of chromosomes during meiosis that creates a new combination of alleles in the gametes (d) the random fertilization of an egg cell by a sperm cell during sexual reproductionarrow_forwardQ2arrow_forward
- Q34arrow_forwardMAKE CONNECTIONS Look at Figure 12.7 and imagine the twodaughter cells undergoing another round of mitosis, yielding four cells.Compare the number of chromosomes in each of those four cells, aftermitosis, with the number in each cell in Figure 13.8, after meiosis. Whatis it about the process of meiosis that accounts for this difference, eventhough meiosis also includes two cell divisions?arrow_forwardIn Drosophila, two genes, one for body color and one for eye color, are carried on the same chromosome. The wild-type gray body color is dominant to black body color, and wild-type red eyes are dominant to purple eyes. You make a cross between a fly with gray body and red eyes and a fly with black body and purple eyes. Among the offspring, about half have gray bodies and red eyes and half have black bodies and purple eyes. A small percentage have: (a) black bodies and red eyes; or (b) gray bodies and purple eyes. What alleles are carried together on the chromosomes in each of the flies used in the cross? What alleles are carried together on the chromosomes of the F1 flies with black bodies and red eyes, and those with gray bodies and purple eyes?arrow_forward
- If the blue F1 females in Figure are backcrossed to the blue males in the P generation, what phenotypes and proportions of offspring will be produced?arrow_forwardWhy is meiosis useful? Select all that apply 1. I produces genetically variable offspring 2. it maintains the chromosome number between generations 3. it reduces the frequency of mutations 4. it provides an alternative route to cell division for cells that fail to complete mitosis 5. It does not require proteinsarrow_forwardDo 24 and 25arrow_forward
