In order to selectively breed larger corn plants, you only collect seeds from the tallest individuals in your current crop. The mean height of the plants in your crop is 100 cm. You have read that the (narrow-sense) heritability of height in similar populations is 0.4, and you have raised your plants in comparable environmental conditions from similar seed stock. You see a response to selection of 8 cm; unfortunately, you forgot to measure the strength of selection by recording the mean height of the parents of this generation. What is your best estimate of the mean height of the parents, given this heritability and response to selection?

A wide-ranging survey of Nicotonia growing in its natural environment recorded a variation in corolla length ranging from 12mm to 47mm with a variance of 36.5. Subsequently, collected seeds were grown in a greenhouse and it was found that the range was now very much lower with most plants having similar corolla lengths and the variance was now only 8.4. What is the heritability of corolla length?
Seed weight in a particular plant species is determined by pairs of alleles attwo loci (a+ a− and b+ b−) that are additive and equal in their effects. Plantswith genotype a− a− b− b− have seeds that average 1 g in weight, whereasplants with genotype a+ a+ b+ b+ have seeds that average 3.4 g in weight. Aplant with genotype a− a− b− b− is crossed with a plant of genotype a+ a+ b+b+.a. What is the predicted weight of seeds from the F1 progeny of this cross?b. If the F1 plants are intercrossed, what are the expected seed weights andproportions of the F2 plants?
A genetically diverse population (Population 1) of monkeyflowers is growing on an alpine slope. The seeds produced by 100 of these plants are counted and the mean and variance are calculated. The variance is 25. One plant is selected and cuttings are taken from it. These cuttings are cultivated in the greenhouse, producing many genetically identical clones of the same plant. These clones (Population 2) are then transplanted into the alpine population, allowed to grow for a year, and then the numbers of seeds produced by each of the cloned plants is counted. The variance in seed number among these cloned plants is 10. Assume that the alpine slope environment does not vary across the years of the experiment, and that there is no genotype-by-environmental variation for seed number. What is the broad-sense heritability for seed number for Population 1?
A wide-ranging survey of Nicotonia growing in its natural environment recorded a variation in corolla length ranging from 12mm to 47mm with a variance of 36.5. Subsequently, collected seeds were grown in a greenhouse and it was found that the range was now very much lower with most plants having similar corolla lengths and the variance was now only 8.4. After the plants had grown to maturity and formed seed, seeds were collected from plants with either the shortest and or the longest corollas in the population and planted separately in the greenhouse. When flowers were formed it was found that the variance of the plants with the shortest flowers was now 4.2 while that of the flowers from the longest seeds had become 13.7 Calculate the new values for heritability in the different groups of plants and explain why this difference may arise.

You are mapping three loci in Brandywine apricot trees (Prunus brandybucki), an important agricultural species in the Shire. In Brandywine apricot trees, sour fruit (fr+) is dominant to fishy-tasting fruit (fr), blue flowers (b+) is dominant to yellow flowers (b), and short, bushy height (sh+) is dominant to tall, tree-like height (sh). You perform a testcross with a plant that is heterozygous for all three loci and get the following offspring: Fruit flavor Flower color Plant height Observed Counts fr+ b+ sh+ 61 fr b sh 53 fr+ b+ sh 11 fr b sh+ 7 fr+ b sh 277 fr b+ sh+ 285 fr+ b sh+ 156 fr b+ sh 150 Total 1000 What is the recombination frequency between b and sh?

Half of the worlds population eats rice at least twice a day. Much of this rice is grown in flooded conditions, and different strains of rice are tolerant (survive) or intolerant (die) under these conditions. Rice breeders used genetic crosses to test whether tolerance to flooding is a dominant trait. Researchers used three true-breeding flood-tolerant strains, FR143, BKNFR, and Kurk, and two true-breeding flood- intolerant strains, IR42 and NB, in the crosses. Results were obtained from three sets of crosses and are reported in the Table below: Results of cross of F1 to tolerant parent: F1 plants were crossed with the tolerant parent of the cross. Number of Plants Progeny Analyzed from Intolerant Tolerant Cross Alive Dead Total 1. F2 results of cross: IR42 FR13A 187 77 264 IR42 BKNFR 192 73 265 NB Kurk 142 52 195 2.

Please refer to the table below. If only data on the variances for F1, F2 and BC1 populations were available, how will the broad sense heritability estimate change? Show solutions.
You have finally gotten a grant to study your favorite tree species, the Spanish pine tree. It has been documented that the height of their trunk varies depending on several factors, however it isn't clear what role genetics plays in this. You travel to Mount Tibidabo to record heights of these trees and start the study. You find that the total variance is 100 feet. You collect some seeds to grow in your gigantic, temperature controlled government forest growing facility. If you want to understand the role of genetics in variation, what can you do in a single experiment to answer this question. Answer in 2-3 sentences
A large, genetically heterogeneous group of tomato plants was usedas the original breeding stock by two different breeders, named Maryand Hector. Each breeder was given 50 seeds and began an artificialselection strategy, much like the one described in the figure. Theseeds were planted, and the breeders selected the 10 plants with thehighest mean tomato weights as the breeding stock for the next generation. This process was repeated over the course of 12 growing seasons, and the following data were obtained: Mean Weight of Tomatoes (pounds)Year Mary’s Tomatoes Hector’s Tomatoes1 0.7 0.82 0.9 0.93 1.1 1.24 1.2 1.35 1.3…
