Flower color is determined by a single locus, where the heterozygote displays an intermediate phenotype. Using the numbers below observed for the 3 phenotypes, calculate p and q Is this population likely to be in H-W equilibrium?
Homework Answers
Answer:
q = 0.775
p = 0.225
Explanation:
Red = RR = 200
Pink = Rr = 50
White = rr = 750
RR 200 = 200*2 = 400 “R” alleles
Rr 50 = 50 R & 50 r alleles
rr 750 = 1500 “r” alleles
Total allele= 2000
Total R alleles = 400+50 = 450
Frequency of R allele = = p = 450/2000 = 0.225
Total r alleles = 1500+50 = 1550
Frequency of r allele =q= 1550/2000 = 0.775

In a population of wildflowers, flower color is controlled by a single locus. Homozygous dominant individuals are red, homozygous recessive individuals are white, and heterozygous individuals are pink. If 16 of 100 flowers are white and 32 of 100 are pink, can you calculate the expected value for FST?

Q: Flower color of a particular snapdragon species is determined by a single gene. Red flower color trait is incompletely dominant over the white trait. Heterozygotes produce pink flowers.If you were to given 6 seeds resulting from F1 cross, what is the probability that 1 will produce red flowers, 3 will produce white flowers and 2 will produce pink flowers?

You are doing and experiment on inbreeding in Phlox plants with a single-locus polymorphism in flower color. WW genotypes have white flowers, PP genotypes have purple flowers, and WP genotypes have magenta flowers. You construct an artificial population in the greenhouse consisting of 50 white-flowered phenotypes and 50 purple-flowered phenotypes. You then cross all individuals randomly and grow out 100 F1 seeds. What are the genotype frequencies among the F1 offspring if you assume Hardy Weinberg equilibrium?

In Andalusian fowl, a single gene determines feather color. Individuals are either white (aa), gray (Aa), or black (AA). The table gives the observed numbers for each phenotype in a wild population of 2,000 birds. Calculate actual allele frequencies, and the three expected phenotypes if the population is in Hardy Weinberg equilibrium for this locus.

1) In peas, a gene controls flower color such that R = purple and r = white. In an isolated pea patch, there are 36 purple-flowering plants and 64 white-flowering plants. Assuming Hardy-Weinberg equilibrium, what is the frequency of the white allele (q) for this population? 2) In an insect population at HWE where 16% of the population displays a recessive phenotype for green eyes conferred by gg, while the rest have black eyes (and are thus GG or Gg),...

Flower color is determined by genetic combination. Let R represent the gene for red flowers and w represent the gene for white flowers. A mixed genetic combination, Rw, results in pink flowers. Consider the offspring of two heterozygous pink, Rw, genetic combination parents. 25. Show how you could use a polynomial to model the possible genetic combinations of the offspring. 26. What percent of the possible genetic combinations result in red-flowered offspring? 27. What percent of the possible genetic combinations...

1. You are studying a color polymorphism in a population of soapberry bugs. A single gene controls color variation; individuals with at least 1 copy of the R allele at this locus are red while individuals of the rr genotype are white. You know that this population satisfies the conditions for Hardy-Weinberg Equilibrium, and that 64% of the population shows the red phenotype. What is the frequency of the R allele? Show your work. 2. Male Trinidadian guppies use bright...

Question 1 (1 point) In a species of flowering plant, petal color is determined by one gene with two alleles, R and W. Individuals homozygous for allele R have red petals, and those homozygous for allele Whave white petals. Ris dominant to W.
