Suppose the mature height of a plant is a multifactorial trait under the control of five independently assorting genes, designated A, B, C, D, and E, and five environmental factors. There are two alleles of each gene (
The five environmental factors are (
Thus, for example, if one environmental factor is optimal, two are good, one is fair, and one is marginal, the loss of potential height is
a. Calculate the potential height, based on inherited alleles, and the attained height, based on growth in the environmental circumstances given, for the three plants (a, b, and c) in the accompanying table.

c. List two genotypes that have a height potential of
d. If two plants that each have a height potential of

- The shape of a pumpkin is determined by the action of two genes A and B. The recessive forms of these two alleles produces a flattened-shaped fruit, whereas the dominant forms of these two alleles produce the typical pumpkin with ridges. When both alleles are heterozygous a disc-shaped pumpkin is produced. If the genotype of the pumpkin plant is homozygous dominant at one allele and heterozygous at the other, the pumpkin will be ball-shaped. If the pumpkin plant is homozygous recessive at one allele and heterozygous at the other allele it produces an oblong-shaped fruit. Plants with genotypes other than the ones listed in this question do not produce pumpkins. Do the following cross: two pumpkin plants capable of making disc-shaped pumpkins are crossed with each other. Based on this cross, answer the following: (Show your work below.) How many of the progeny will make ball-shaped pumpkins?__________________________________________ How many of the progeny will make disc-shaped…arrow_forwardConsider the following hypothetical gene a plant.Gene T produces a protein that impacts stem length.There are two alleles for gene T, T which produces long stems and t which results in short stems. Assume that gene T displays complete dominance, what would be the genotypes (written as two letters-your answer will be case sensitive) that correspond to- homozygous dominant, homozygous recessive and heterozygous. and the phenotypes (what trait will be observed in the plant) for each of the genotypes.arrow_forwardExamine the trait distribution of Specific Leaf Area (The ratio of leaf area to dry mass, SLA), below. The dotted normal distribution represents the natural pattern of SLA observed in nature. The histogram below the dotted curve represents the distribution of phenotypes when the plant is grown in a single common environment. The numbers above the bars represent the observed phenotype ratio. a a) How many polygenes encode for this trait? b) Assuming the minimum observed phenotype in a common garden was 8sqm/kg and the maximum observed phenotype was 20 sqm/kg, what is the contribution of each allele in this polygene?arrow_forward
- A heterozygous plant with genotype Aa self-pollinates, and then its offspring also self-pollinate. Find the probability that the offspring of the offspring are tall for the following genetics systems. Half of heterozygous plants and one fourth of homozygous plants are tall (it depends on their position in the greenhouse).arrow_forwardIf an allotetraploid species is made up of two ancestral genomes, A and B, with each of them having a basic chromosome number of seven. The resistance to the pathogen attacking the foliage of plants is controlled by a dominant allele located at the F locus. The recessive alleles F^a and F^b show sensitivity to the pathogen. Plants with at least on F^A allele are resistant to the pathotype 1 and 2 (regardless of the genotype in B genome), and plants with at least one F^B allele are resistant to pathotypes 1 and 3 (regardless of genotype in A genome). What proprtion of the self-progeny of F^AF^a F^BF^b plant will be resistant to pathotype 1, 2 and 3?arrow_forwardA heterozygous plant with genotype Aa self-pollinates, and then its offspring also self-pollinate. Find the probability that the offspring of the offspring are tall for the following genetics systems. Only plants that have two A alleles are tall.arrow_forward
- On pea plants, the location of flower growth is an inheritable trait. Axial flower position (A) is dominant over the recessive trait of terminal flower position (a). In the parental generation, a homozygous dominant axial flower position pea plant is crossed with a terminal flower position pea plant. 1. Draw a digital Punnett square of the F1 offspring producing the F2 offspring. 2. In the F2 generation, what is the probability one plant will have a terminal flower position? 3. In the F2 generation, what is the probability two plants will have axial flower positions?

In flowers, T codes for tall stems and P codes for purple flowers. Jonathan crosses two heterozygotes that produce 544544 offspring. How many of these 544544 offspring are predicted to have both short stems and white flowers? please help solve and please explain thank youarrow_forwardwhat is the answer to this question with solution of a punnet squarearrow_forward
- What is the answer to this genetics problem.arrow_forwardAssuming you planted bean seeds that have been obtained from the same parent bean plant in three plots where growth conditions are the same except soil pH which varies as shown in the table attached which shows the effects of soil fertility on bean yields obtained from three plots where seeds from the same parent bean plant were obtained. a) is the trait, bean yield, qualitative (monogenic ) or quantitative (polygenic). Supoort tour answer with good reasoning.arrow_forwardIn rice, plants homozygous for the recessive allele sd1 are relatively short in stature; heterozygotes are of normal height. Plants carrying one copy of a dominant allele, Xa4 (corresponding to a second gene located on a different chromosome), are resistant to bacterial blight. Note that both the sd1 and Xa4 alleles would be considered "mutant" alleles in this scenario. A farmer obtained two pureline plants (one is homozygous for the sd1 mutant and the other is homozygous for the Xa4 mutant) and crossed them. Assume both pureline plants have identical alleles at all other loci, and no other mutant alleles are present in these two plants, which of these statements is correct? O All the progeny will be susceptible to bacterial blight and will be short. O When a progeny plant from the cross goes through meiosis, gametes will either contain sd1 or Xa4 alleles, but never both. O When a progeny plant from the cross goes through meiosis, four possible types of gametes that may form, and the…arrow_forward
