Consider an individual with the AB/ab genotype, and assume that alleles of the A and B genes are unable to recombine during meiosis. If this individual is crossed with an individual who is homozygous recessive at both genes (ab/ab), what is the expected phenotype ratio in the offspring?

An individual that is homozygous AABBcc is crossed to an individual that is homozygous aabbCC producing F1 individuals with genotype AaBbCc. Assume that the A, B, and C loci are all on the same chromosome. One chromatid at the start of meiosis (before crossing over) has the alleles A, B, and c. What alleles are on its sister chromatid? What alleles are on the homolog? Group of answer choices A. Sister chromatid ABc, Homolog no way to tell B. Sister chromatid ABC, Homolog abc C. Sister chromatid ABc, Homolog abC D. Sister chromatid abC, Homolog ABc
During the process of Meiosis an individual's alleles for each trait are independently sorted to make unique gametes. A person is heterozygous for the Freckles phenotype (Ff) and also heterozygous for the PTC-tasting phenotype (Tt). This person's genotype for these two traits is represented as FfTt. A) How many unique gametes could be produced by this individual if you consider these two traits? B) List the different allele combinations that could result.
Consider an individual with genotype P/p; Q/q. Assume no crossing over. What is the total number of possible genotypes of gametes that may be produced by this individual?
In the following cross, imagine that you have a female fly that has two Xs and one Y due to a nondisjunction event in her mother's germ cells. Draw out what the possible gametes are for both the female and the male and also a Punnett square showing the genotypes, phenotypes, and sex of the possible flies as a result of this cross. You do not need to provide the probabilities of each of these. Red-eyed wi C Ở Red-eyed wt XX Y X Y Meiosis
In Figure 4-3, would there be any meiotic products thatdid not undergo a crossover in the meiosis illustrated? Ifso, what colors would they be in the color conventionused?
A female of genotype a b c + + + produces 100 meiotic tetrads. Of these, 68 show no crossover events. Of the remaining 32, 20 show a crossover between a and b, 10 show a crossover between b and c, and 2 show a double crossover between a and b and between b and c. Of the 400 gametes produced, how many of each of the 8 different genotypes will be produced? Assuming the order a–b–c and the allele arrangement previously shown, what is the map distance between these loci?
Assume that the trihybrid cross AABBrr x aabbRR is made in a plant species. Assume that A and B are dominant alleles, but there is no dominance effect of alleles at the R locus. a) How many different gametes are possible in the F1generation? What are the genotypes of these gametes? b) What is the probability of the parental aabbRR genotype in the F2 progeny? c) What proportion of the F2 progeny would be expected to be homozygous for all three genes?
In tomatoes, red fruit is dominant to yellow fruit, and purple stems are dominant to green stems. Thegenes encoding these traits are on different homologous chromosomes. The progeny from a matingconsisted of 305 red fruit, purple stem plants; 328 red fruit, green stem plants; 110 yellow fruit,purple stem plants; and 97 yellow fruit, green stem plants. What would be the genotypic and phenotypic outcome if each parent was self-fertilized?
In a diploid organism of genotype A/a; B/b: D/d, the allele pairs are all on different chromosome pairs. The panels in Figure 1 purport to show anaphase in individual cells. Assuming no crossing over, state whether each panel in Figure 1 represents anaphase occurring during meiosis I, meiosis II, mitosis or is impossible for this particular genotype.
In a cross between two, dihybrid, heterozygous individuals, what fraction of the offspring will be dominant for only the (A) gene?
Consult Figure 4, which shows the distribution of chromosome segregation for a cell with genotype M/m; B/b. For each panel, state whether the illustration is possible for mitosis, meiosis I, meiosis II, or not possible for the genotype. Assume no crossing over. Panel C: Possible during mitosis Possible during meiosis I Possible during meiosis II Not possible for the stated genotype Panel D: Possible during mitosis Possible during meiosis I Possible during meiosis II Not possible for the stated genotype
