In Hereford cattle, the phenotypic expression of coat pattern called line-back (a white line down the center of the back, extending almost to the tail) is considered undesirable. The gene which causes line-back is recessive and autosomal. If 7 cows out of 100 cattle express this trait, what is the allele frequency for this trait? If the line-back cows are not included in the mating population (W22=0), how many line-back cows will be found in the next generation? (Assume 100 cows in the next generation.) can u ansewer the second question
In an ideal population of plants with red (due to dominant “R” allele) or white flowers (due to recessive “r” allele), the frequency of white flowers is 9%. Draw a Punnett square and identify the location of the white flowered plants within the square using the color red. Identify where the “R” allele is designated on the Punnett square using the color green. What is the frequency of the “R” allele?
a) 9% b) 30% c) 91% d) 70%
In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.

- In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y). In a population of 24 pea plants, 15 pea plants are homozygous dominant, 6 are heterozygous dominant, and 3 are recessive. Find the frequency of the following YY, Yy, yy. Show all work and record your response using three significant digits.arrow_forwardThe ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele (t) cannot taste PTC. In a population consisting of 500 individuals, 347 are tasters and 153 are non-PTC tasters. Calculate the frequency of the T and t alleles in this population, and frequency of the genotypes. (Please train yourself to use the Hardy-Weinberg equation.) To present your answers, follow the format in the picture below.arrow_forwardA particular species of flowering plant comes in three colors: Red, Blue, and Purple. Red is considered homozygous dominant, blue is considered homozygous recessive, and purple is considered heterozygous. Please use F to represent dominant alleles and f to represent recessive alleles. A member of this plant species that makes red flowers cross-pollinates with a member of the same species that makes blue flowers. In your answer, please state the mode of inheritance, the genotypes of both parents, and the genotypic and phenotypic ratios of the offspring.arrow_forward
- There is a gene that causes people to have crumbly earwax. This gene is expressed as a complete dominant: Individuals who are homozygous dominants (CC) or heterozygous (Cc) have crumbly earwax. Homozygous recessives (cc) have gooey earwax. There are 100 people, 64 of whom have crumbly earwax. Assuming Hardy-Weinberg conditions, what is the frequency of the c allele on Paradise Island?

The green lizards comprise only 4 percent of the population whereas the brown lizards comprise the rest. Over a long period of time, increased rainfall in the area leads to transformation of the habitat, with growth of shrubs and small trees. The brown and green lizard numbers almost reverse with the green lizards approaching 81 percent of the total population. Calculate the allele frequency for the green skin color before and after the climate change occurred. Why did the brown lizard, which initially had greater relative fitness than the green lizard, reduce in number drastically?

In the sample, 421 have blood type A, 168 have blood type B, 336 have blood type O, and 75 have blood type AB. Part A Use this information to determine the frequency of ABO blood group alleles in the sample. Recall that when considering genes with three alleles whose frequencies are represented by the variables p, q, and r, the sum of genotype frequencies resulting from trinomial expansion is: (p+q+r)² =p² + 2pq+q2+2pr+r²+2gr = 1arrow_forward

Your study population has genotypic frequencies of HH= 0.6900, Hh= 0.2885, and hh= 0.0215. Part A: What color are heterozygous plants?

The heterozygote Dd is intermediate in color. In a heterogeneous environment, the allele frequencies are D = 0.7 and d = 0.3. This polymorphism is maintained because the environment has some dimly lit forested areas and some sunny fields. During a hurricane, a group of 1000 insects is blown to a completely sunny area. In this environment, the fitness values are DD = 0.3, Dd = 0.7, and dd = 1.0. Calculate the allele frequencies in the next generation.arrow_forwardIn a population of 100 pea plants, there are two variations for flower colors-- purple and white.
