The disorder known as cystic fibrosis (CF) is inherited in a recessive autosomal manner. In populations of Northern European descent, the frequency of people with CF is about 1 in 2,500. Assuming Hardy-Weinberg equilibrium for this disorder, answer the following: A. Assuming Hardy-Weinberg equilibrium, what percentage of people in the population would be expected to be heterozygous carriers

Answer:

The correct answer is -

A. 3.9% people in the population would be expected to be heterozygous carriers

Explanation:

The genotype frequency for the CF affected is 1/2,500,

= 1/2500

= 0.004. This is equal to q^2

here q = frequency of recessive alleles combination or CF people. (H-W equation => p^2+q^2+2pq=1)

The allele frequency is the square root of q^2 value, which equals 0.02. The frequency of the dominant allele or p would be

1 - 0.02 = 0.98 (p+q = 1)

The frequency for the CF combinantion =0.004

the dominant or unaffected people genotype

= (098)^2

= 0.96;

and for the heterozygote, it is

= 2pq

=2(0.98)(0.02)

= 0.039 or 3.9%

A group of researchers has made the claim that one particular butterfly species is the sole pollinator of a tree species and that consequently, the decline of the butterfly population will endanger the survival of the tree species. Data were collected and are summarized below. Which of the following data could best be used to either justify or refute the claim the researchers have made about the interdependence of the butterfly species and the trees?

Tree flower size Number of butterfly visits per flower per day Nectar energy per pollination visit (joules) Fruits per flower
Small 1 10 0.88
Medium 9 12 0.79
Large 55 13 0.85

a. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.
b. The data collected for large flowers are most useful in justifying the claim, because they show that a large number of butterflies visit flowers of this tree species, obtain energy from nectar, and cause fruit production.
c. The data comparing the number of butterfly visits with the size of the tree flowers are most useful in refuting the claim, because they show that the butterfly does not visit all types of tree flowers.
d. The data showing the nectar energy available for all sizes of flowers are most useful in justifying the claim, because they show that butterflies benefit from the relationship with the tree by obtaining energy from tree nectar.

In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

The student then crosses the F1 plants with one another and records 64 red-flowered plants, 107 pink-flowered plants and 53 white-flowered plants. What is the inheritance pattern for flower color in these poinsettias

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaf litter disappears quickly, thereby altering biogeochemical cycles. You conduct an experiment to compare the nitrogen cycle in soils with and without non-native earthworms. Predict the results of your experiment.
