The genotype for a single gene (Br) was determined in a population of tomato plants and the genotypic frequencies were found to be:

.50 BrBr .40 Brbr .10 brbr

Each individual in this population was inbred by self-pollination and the subsequent population was again self-pollinated. What would be the expected frequencies of heterozygous and homozygous recessive individuals in the resulting population? Choose the best answer.

In a species of mouse, tail length is controlled by genes at a single locus, with the long tail allele dominant to the short tail allele. A population has 44 long tail and 36 short tail mice, with 27 of the long tail mice having a homozygous dominant genotype. Is this population in equilibrium?

In the tomato, flower color is determined by alleles of a single autosomal gene. Flowers are found in three colors: Violet, blue and white. When truebreeding violet-flowered plants are crossed with truebreeding white-flowered plants, the result is all blue-flowered plants. What would you predict to be the phenotypes among 240 progeny plants if the blue-flowered plants are crossed with violet-flowered plants? 60 violet, 120 blue, 60 white 240 violet 240 blue 120 violet, 120 blue 120 blue, 120 white 180...

Seed color in radishes is determined by a single gene. Radish seeds come in three colors: purple, brown and orange. A gardener plants all purple seeds in his isolated garden and collects the resulting seeds produced. 157 purple, 73 brown and 81 orange seeds were collected. What type of inheritance does this represent? What is the most probable genotype of each parent? Based on your answer above, what genotypic and phenotypic ratios are expected in these progeny?

A population of 100,000 Arabidopsis thaliana plants is initially at Hardy-Weinberg equilibrium for the A gene, where two alleles, A1 and A2, are present at equal frequencies. The population undergoes 2 generations of 100% self-fertilization. a) After 2 generations of selfing, what are the expected values for: 1) genotype frequencies, 2) allele frequencies, and 3) the population inbreeding coefficient. (The math is easiest using fractions.)

A boy is born with an autosomal recessive genetic disease that is determined by a single-gene defect. Both his parents are unaffected. What is the most accurate statement can we say about the parents genotypes with respect to the relevant locus? In the following statement there are 2 fill in spots, i am providing the options given at these spots and putting them in bold, and in parentheses. (ONE/BOTH) of his parents must be ["homozygous", "heterozygous"] for the disease-causing allele

You are studying hair color in a population of cattle.  You have determined that cattle that are homozygous for one allele (the “red” allele) have red hair and cattle that are heterozygous (for the “red” allele and the “white” allele) have a mix of red and white hair.  You never observe live cattle that are homozygous for the white allele and have determined that cattle with this genotype have white hair but do not survive and are always stillborn.  In your population, 75%...
