23. Flies with red eyes are homozygous (RR) for the reddish eye pigment.
Flies with orange eyes are heterozygous (Rr), and white-eyed flies are homozygous recessive (rr).
You have a population with the following frequencies
36 red eyes + 48 orange + 16 white eyes.
i. Determine the allele frequencies for R and r.
R =
r =
ii. What are the phenotypic frequencies predicted by Hardy-Weinberg?
iii. Is this population at Hardy-Weinberg equilibrium?
Homework Answers
i)
p = 2NRR + NRr / 2N
= 72 + 48 / 200 = 0.6
q = 2Naa + NAa / 2N
= 32 + 48 / 200 = 0.4
Hence, p = 0.6 , and q = 0.4
R = 0.6 , r = 0.4
This is in hardy weinberg equilibrium, p + q = 0.6 + 0.4 = 1
ii) Phenotypic frequencies
RR = 36/ 100 = 0.36
Rr = 48 /100 = 0.48
rr = 16/100 = 0.16
iii) Yes the population is in hardy weinberg equilibrium , p + q= 1

29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes. The...

In Drosophila, the X-linked recessive mutation vermillion (v) causes bright red eyes, in contrast to the brick-red eyes caused by the wild-type allele. A separate autosomal recessive mutation, brown (bw), causes flies to have brown eyes. Flies carrying both mutations have no eye pigmentation and are white-eyed. Determine the F1 and F2 phenotypic ratios for each sex from the following crosses: (a) brown females X vermillion males (b) white-eyed females X wild-type males
Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to a...
Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to a mutation in a gene on the X-chromosome. The white eyed phenotype is X-linked recessive. The sex chromosomes in fruit flies are: females, normally XX; males, normally XY. If a red-eyed female who is a carrier of the white eyed allele (normal or wild-type phenotype) mates with a white-eyed male (mutant phenotype), what is the likelihood that their male offspring will have red eyes? Parents:...

B. Geneticists have discovered that some flies have white eyes and others red eyes. The difference in eye color is due to inheritance of one gene. Two true-breeding flies are mated, with the female white-eyed and the male red-eyed. The F1 are 1/2 red eyed and female, and 12 white-eyed and male. (There are no white-eyed females, or red- eyed males.) 11. The F2 includes: 54 red-eye females 42 white-eyed females 48 red-eyed males 56 white-eyed males Phenotypes d (o-edd/e...

A population of flour beetles has 1000 individuals. Normally the beetles are red in color; however, this population has a utation in the gene for body color that results in black beetles that are designated by the rr genotype. Red body color is dominant to black so the genotypes RR and Rr result in red beetles. Assume the population is in Hardy-Weinberg equilibrium, with a 50% frequency of each allele for body color. A) --- what is the frequency of...

Some fruit flies have an autosomal mutation that causes the recessive white-eyes to appear compared to the wild-type (dominant) red eyes, while others have an X-linked mutation that causes the same varieties. You are presented with two populations of flies in unmarked tubes: one that has the autosomal white-eye mutation, and a population that has the X-linked mutation for white-eye. Assuming you have separated the pure breeding red and white-eyed parents in each population, What is the set of two...

If an apterous female fruit fly with wild type (+) red eyes is crossed with a white eyed male with normal wild type wings, what is the resting F1 generation? Please show on a punnet square.Also what is the punnet dihybrid cross for the F2 generation. Note: the recessive white eyed allele is X-linked while the apterous (wingless) recessive allele is NOT x-linked. SO to summarize: male with recessive white eyes and with normal wild type wings and a recessive...
