In normal plants, the probability that an offspring of a heterozygous parent is heterozygous is 0.5. If the survival of heterozygous offspring differs from that of homozygous offspring, the probability that a surviving offspring is heterozygous may not be equal to 0.5. For the following values of the probability, write a discrete-time dynamical system for the fraction of heterozygous offspring over time, find the solution, and compute the fraction that will be heterozygous after ten generations. How does this compare with the fraction for a normal plant? The probability that an offspring is heterozygous is 0.6.
A gardener grows two different colors of apples under exactly the same environmental conditions. Red apples have a heritability of 0.14 for the value of apple weight, and green apples have a heritability of 0.41 for the value of apple weight. The gardener plotted the number of apples present at each weight. Which graph would you hypothesize represents the red apples? Number of apples Weight GRAPH A Number of apples Weight GRAPH B O Graph A O Graph B There is not enough information to make a hypothesis.
A species of butterfly shows variation in the length of the antennae. You measure antennae in a butterfly population and find the mean to be 15 mm. You calculate a heritability of antennae length to be 1 (h2 = 1). %3D That summer, there is a severe drought. Many of the butterflies die and only a few survive to reproduce. The surviving butterflies have a mean antennae length of 17 mm. a) What is the predicted mean limb-length of the offspring of the surviving butterflies? [ Select ] b) What type of selection was acting on antennae length in these butterflies? [ Select ] c) Five years later, you go back and measure antennae length in this butterfly population again. Every butterfly in the population has antennae measuring 16 mm. What is the heritability of antennae length in this population now? [Select ]

This phenomenon, known as heterosis, led to tremendous increases in corn production in the United States. In 1931, 0.1 percent of the corn planted was hybrid corn, resulting in an average yield of 24.5 bushels per acre. In 1992, almost all corn planted in the United States was hybrid corn, resulting in an average yield of 135 bushels per acre. Study the figure at the bottom of the page, which shows the current method for producing hybrid corn. Explain the…

The mean of plant height from two rice plants (P1 and P2) and their progeny (F1 and F2) and a backcross generation (P1 x F1) are shown below. Population Mean (in) P1 34.1 P2 65.2 F1 44.1 F2 46.2 BC1 39.6 Explain the possible reasons for the observed differences in the sample means. Account for the differences in the sample means of P1 and P2. Similarly, account for the differences in the sample means of the F1 and F2. Compare the difference in the parental generations with that in the filial generations.

In eggplants, fruit color is due to two alleles with the Purple allele (CP) incompletely dominant over White (CW). Plants that are heterozygous for this allele produce light violet colored fruit. A biologist surveys a field of eggplants that has been left alone for several years, allowing the eggplants to reproduce and grow without harvesting or disturbance. She finds that 600 of the plants make purple fruits, 200 make light violet fruits, and 200 produce white fruits. Calculate p (fraction of CPalleles in the populations): Calculate q (fraction of CWalleles in the populations): If this population of plants is at Hardy-Weinberg Equilibrium, what fractions (round to two decimal places) of the next generation of egg plants will produce Purple, White, and Violet fruits? Purple: Violet: White: If the frequency of white alleles was actually much higher in next generation than expected, and continued to increase in future generations, and the population stays relatively large, what type of…
