In corn, a triple heterozygote was obtained carrying themutant alleles s (shrunken), w (white aleurone), andy (waxy endosperm), all paired with their normal wildtype alleles. This triple heterozygote was testcrossed, andthe progeny contained 116 shrunken, white; 4 fully wildtype; 2538 shrunken; 601 shrunken, waxy; 626 white;2708 white, waxy; 2 shrunken, white, waxy; and 113 waxy.a. Determine if any of these three loci are linked and,if so, show map distances.b. Show the allele arrangement on the chromosomesof the triple heterozygote used in the testcross.c.

In a cross between two varieties of corn, gl1gl1Ws3Ws3 (egg parent) * Gl1Gl1ws3ws3 (pollen parent), a triploid offspring was produced with the genetic constitution Gl1Gl1gl1Ws3ws3ws3. From which parent, egg or pollen, did the 2n gamete originate? Is another explanation possible? Explain.
n corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of the corn plants (i.e the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male sterile lines sing the cardboard chips, simulate the crosses indicated below. Give the genotypes and phenotypes of the offsprings in each cross, and properly label the nucleus and the cytoplasm of each individual in the cross Legend male sterile cytoplasm Male fertile cytoplasm FF nucleus Ff nucleus ff nucleus A.

REad and analyzed the following genetic problem. Show complete solution (Genotypes of P, Punnet Square and GR,PR). 1. In the garden peas, green pod color is dominant over yellow pods. Also, round seed shape is dominant over wrinkled seed. Cross fertilization was done between a pea that is homozygous dominant for pod color with heterozygous round shape and another pea that is heterozygous for both pod color and seed shape. Determine the genotypic and phenotypic ratio of teh offspring.
Given the following pathway on the image: G and H are dominant alleles of the two independently assorting genes that produce an enzyme that catalyzes the conversion of one pigment to another, and g and h are recessive alleles that are non-functional. A true-breeding blue plant is crossed with a white plant of genotype ggHH. The F1s are allowed to self-mate. 1. What proportions would you expect in the F2 progeny? 2. Which is the epistatic allele?
A cross is carried out between two pure lines of tomato plants, one having regular leaves and red fruit and the other having potato leaves and yellow fruit. The F1 generation all have regular leaves and red fruit. The F1 individuals are then crossed with one another. Question text The expected phenotypic ratio for leaf shape and fruit colour genes is 9:3:3:1, if both genes are on different chromosomes and assort independently during gamete formation. The information below represents two sets of data collected from the above cross. Data Set 1 is from a population of 5000 tomato plants and Data Set 2 is from a population of 50 tomato plants. Phenotypes Observed Probabilities Data Set 1(N = 5000) Data Set 2(N = 50) Regular Red 0.58 0.050 Regular Yellow 0.16 0.29 Potato Red 0.20 0.050 Potato Yellow 0.060 0.61 A.
