the aggresive behavior in cats is controlled by a completely dominant gene locus A. There are 46 docile cats in subdivision with a population of 158. Question: Determine if how many animals are heterozygous and how many animals have the dominant allele? provide solution

If the population is in Hardy-Weinberg equilibrium, what is the expected (projected) frequency of heterozygous cats in the next generation?   Question 4 options:   0.68   0.89   0.435   0.84

In carnations, the red pigment (RR) is incompletely dominant to white (rr). The heterozygote (Rr) is pink. In a randomly mating field of carnations, 42 plants were red, 178 plants were pink, and 180 plants were white (total =400). What is the best estimate of the allele ferequency, for the red allele in this population?

Consider the B locus which has two alleles in a population: B and b. Researchers examined the genotypes several individuals for this locus and obtained the following numbers  B/B: 320individuals B/b: 60individuals b/b: 12individuals If the B locus is at Hardy-Weinberg equilibrium, what would the expected number of individuals with the Bb genotype? Round your answer to the closest full number.

Consider a gene with two alleles, L and M, that exhibit complete dominance. The table below provides the relative fitnesses of the three genotypes in two populations. LL LM MM Population 1 0.8 0.3 0.3 Population 2 0.9 1.0 1.0 a. Which allele is dominant, and how do you know? b. Which allele will increase (in each population), and how do you know? c. In which population will the change in allele frequencies occur more quickly, and how do you know?

A population is solely comprised of 152 A2A2 individuals.  7 A1A1 individuals migrate in and contribute to the mating pool.  What is the frequency of A1A2 individuals in the offspring?

In a Gecko population a group of Geckos skin color is controlled by one gene with two alleles "R"which codes for red and is dominant to "r" which codes for yellow and is recessive. If 100 Geckos are on the island and you gene test them to know their alleles you'll observe that 30 are homozygous red, 60 are heterozygous red, and 20 are homozygous recessive. Determine the Chi-square. assuming the original parents (Rr xRr).* Hint: determine the expected first before plugging into the equation awesome as this one? REGISTER NOW 13 5 11 4 D

In pea plants, the color purple is dominant to the color white. A farmer with an isolated patch of pea plants counts 36 purple-flowering plants and 64 white-flowering plants. Assuming the patch is in Hardy-Weinberg equilibrium, what is the frequency of the white allele? 0.75 0.64 0.80 0.36

A wild population of pea plants has two alleles for flower colour in its gene pool. A dominant allele (P) specifies purple flowers; a recessive allele (p) specifies white flowers. If the frequency of allele P is 0.75, what is the expected frequency of p

In a certain breeding population, it is known for certain that only 9.8% of the individuals are "true-breeding" for the dominant phenotype. What would be the predicted frequency of individuals that are "true-breeding" for the recessive phenotype?
