A population of water snakes is found on an island in Lake Erie. Someof the snakes are banded and some are unbanded; banding is caused byan autosomal allele that is recessive to an allele for no bands. Thefrequency of banded snakes on the island is 0.4, whereas the frequencyof banded snakes on the mainland is 0.81. One summer, a large numberof snakes migrate from the mainland to the island. After this migration,20% of the island population consists of snakes that came from themainland.a. If both the mainland population and the island population are assumedto be in Hardy–Weinberg equilibrium for the alleles that affect banding,what is the frequency of the allele for bands on the island and on themainland before migration?b. After migration has taken place, what is the frequency of the allele forthe banded phenotype on the island?
Cystic fibrosis is a homozygous recessive condition that affects 1 in 10,000 of the Hispanic populationin the United States. Calculate the frequency of the dominant allele, the frequency of the recessiveallele, and the percentage of heterozygous individuals (carriers) in the Hispanic population.Frequency of thedominant alleleFrequency of therecessive allele% homozygous dominant% homozygous recessive% heterozygous
In domestic chicken, feather colour and shape are two traits which are controlled by autosomal alleles that are co-dominant. Table 2 shows the alleles and phenotype of both traits. The heterozygous state for feather colour is grey while the heterozygous state for feather shape is mildly frizzled. TABLE 2 Trait Feather colour Allele CB CW SS SF Effect Produces black feathers in homozygotes Produces white feathers in homozygotes Produces straight feathers in homozygotes Produces frizzled feathers in homozygotes Feather shape A farmer bred a black frizzled rooster with a grey mildly frizzled hen. Draw a genetic diagram to show the expected results of this cross. Include in your answer the phenotypic ratios. Is it necessary to do a test cross to determine the genotypes of the offspring? Explain your answer. The farmer would like all his chickens grey and mildly frizzled. What would you advise him to do? Explain your answer.
Heterozygote advantage is an interesting condition in those individuals who have one of each allele (dominant and recessive) have a higher survival rate than those individuals who are either homozygous dominant or homozygous recessive. Sickle-cell anemia is such a genetic disease associated with the recessive allele. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause mortality. In addition, malaria cannot survive well within these "partially defective" red blood cells. Thus, heterozygotes tend to…
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
Both Duchenne muscular dystrophy and color blindness are caused by recessive alleles. DMD, unlike color blindness, nearly always occurs in males. Explain why.
In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
n an example of recessive epistasis the deposition of pigment into hair follicles of the Labrador Retriever is governed by a dominant gene (C) and lack of deposition by its recessive allele (c). Lack of pigment deposition produces a yellow coat color. The color of pigment is governed by an independently assorting hypostatic gene, the dominant allele (B) produces black pigment and its recessive allele (b) produces brown. What coat color ratio is expected from the cross of a brown dog (bbCc) to a black dog (BbCc)? 1/2 brown, 1/2 black 1/4 black, 1/4 brown, 1/2 yellow 1/2 black, 1/4 brown, 1/4 yellow 3/8 black, 1/8 brown, 1/2 yellow 3/8 black, 3/8 brown, 1/4 yellow
The presence of second allele (E) affects the coat color of German Shepherd. In particular, the presence of homozygous recessive ee produces yellow German Shepherd.
