Imagine a population 528 individual plants. In this population, 4 % of the plants produce red flowers, and 9 % produce pink flowers. The remaining plants produce white flowers. Flower colour is attributed to a single locus with two alleles. Red flowers are produced by plants that are homozygote for the R allele. White flowers are produced by plants that are homozygote for the W allele. Heterozygotes (RW) produce pink flowers. What is the expected (under Hardy-Weinberg equilibrium) number plants producing pink flowers in this population? Round your answer to the closest full number.
In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y).In a population of 10 pea plants, 5 pea plants are homozygous dominant, 3 are heterozygous dominant, and 2 are recessive.Find the frequency of thea.

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?
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?
Eye color in a species of fruitfly is determined by a single locus with two alleles: E and e. EE individuals have red eyes, Ee have pink eyes, and ee individuals have brown eyes. In a lab population that is in Hardy- Weinberg equilibrium, we count 34 flies with brown eyes out of 144. How many flies can you expect to have red eyes? Round your answer to the closest integer value.
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 snails, a locus affecting shell color has 2 alleles. The D allele produces a dark shell, while the d allele produces a white shell. Heterozygote individuals (Dd) have a yellowish shell. In a sample of 150 snails, 47 snails have a white shell, and 12 have a yellow shell. What is the frequency of the D allele? Round your answer to the second decimal place (0.00)
A scientist is studying a wild population of Japanese morning glories. It is easy to separate genotypes at a flower color locus by their phenotypes. Red individuals are homozygous for the R allele, yellow individuals are homozygous for the Y allele, and orange individuals are heterozygous. If the number of individuals with the following genotypes are: RR: 831 RY: 33 YY: 442 Is the population in Hardy Weinberg Equilibrium?
Eye color in a species of fruitfly is determined by a single locus with two alleles: E and e. EE individuals have red eyes, Ee have pink eyes, and ee individuals have brown eyes. In a lab population that is in Hardy–Weinberg equilibrium, we count 28 flies with brown eyes out of 172. How many flies can you expect to have red eyes? Round your answer to the closest full number.
The Andalusian fowl exhibits codominance. The genotypes and phenotypes of Andalusian fowls are shown in the diagram below. White Black Speckled Phenotype White Black Speckled Genotype WW BB BW In a small community south of Seville, the capital city of Spain, speckled hens can be sold for more money at the market then black or white hens. Which of the following rows correctly identifies the cross the farmer should perform to ensure all of his eggs produce speckled offspring AND the phenotypes of offspring produced from crossing a white hen with a speckled rooster? Select one: a. Parental cross to produce Speckled offspring Phenotypes of offspring produced from crossing a white hen and a speckled rooster BB BB White, speckled, and black offspring b.

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 ]
