In a population of 1000 people, 600 are homozygous dominant, 150 are heterozygous and 250 homozygous recessive. what is the frequency of the dominant allele? a67.5 b77.5 c87.5

A population of 30 hamsters have either a black coat (BB or Bb) or a white coat (bb). There are 10 BB homozygotes, 10 Bb heterozygotes, and 10 bb homozygotes in the population. What is the frequency of the b allele in this gene pool? 10% 30% 50% 67%

What is the chi-square value of the pumpkin population? round up and use four decimal points After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size.

Say you have a lab population of 1000 dragonflies that is in Hardy Weinberg equilibrium.  Body color is determined by a single gene with 2 alleles. The white body color phenotype is due to the homozygous recessive phenotype.  Out of the 1000 dragonflies, 250 are white.  Heterozygous and homozygous dominant individuals are green. How many of the 1000 dragonflies are heterozygous?   Group of answer choices 25 250 500 50 125

What is the selective factor, or selective environment, which allows carriers of the sickle-cell allele to have higher fitness than other genotypes? Group of answer choices A-Africa B-sickle-cell disease C-AIDS D-malaria

Given a population with 0.45 homozygote dominant individuals, 0.15 heterozygotes and 0.4 homozygote recessive individuals, determine the total frequency of dominant alleles in the population. 0.52 0.45 0.6 0.15 0.4

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

If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele?

In a population of 500 individuals, 70% are homozygous dominant for the A allele. What percentage of the population is heterozygous for the A allele? a) 10%   b) 20%   c) 30%   d) 40%
