I'm confused about how I would figure out these two questions as I don't really understand the difference or where to start. What would genotypic frequencies be for Wildrose at pt-8 if it were in equilibrium? and How many individuals (to 2 decimal places) of each genotype would there be from Wildrose at pt-8 if it were in equilibrium?
at Tools Add-ons Help Last edit was 22 minutes ago rmal text I UA Calibri 12 | 5 EE E6 Section 4: Monohybrid test cross A monohybrid cross is a mating where alleles of just one gene are tracked in the offspring. A test cross is a mating in which two parents (P generation) are crossed to give F1 (first filial generation) offspring, and then two F1 parents are crossed to give F2 (second filial generation) offspring. By tracking offspring through two generations, a test cross can reveal patterns of inheritance for particular genes. 9. In a cross between a b.ck and a white guinea pig, all members of the F1 generation are black. The F2 generation is made of % black and 4 white guinea pigs. Diagram this cross, and list the genotypes and phenotypes for each generation. !!

For the purpose of the assignment, we will refer to XY individuals as male and XX individuals as female. In humans, colorblindness (b) is an example of an X-linked recessive trait. In this problem, a male with colorblindness XbY marries a female who is not colorblind but is a carrier of the colorblindness allele (XXb). Using a Punnett square, determine the genotypic and phenotypic probabilities (as percentages) for their potential offspring. Give the percentages in numbers, without the percent sign, for each genotype and phenotype. Genotypes XX Xxb xbxb XY xby Phenotypes Consider females (XX) individuals only. In the two questions below, I am asking for the % of females, not % of all people. What is the % of females who are not colorblind? What is the% of females who are colorblind? Now consider makes (XX) individuals only. In the two questions below, I am asking for the % of
About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness; so What percentage of women would be expected to be heterozygous?
The next two questions go together. Again with the llamas that display an extraordinary range of fur colors - individuals are either blue, red, or green. But in this isolated population the epistatic relationships between the A and B loci are different. You mate a homozygous red-furred llama (Parent #1) with a homozygous green-furred llama (Parent #2), and all of the offspring are red. You interbreed these red F1s, and the resulting F2 generation consists of 93 red llamas, 27 blue llamas, and 9 green llamas. Assign the genotypes to a modified 9:3:3:1 ratio. red: blue: green What type of epistasis is acting?
Imagine a population 528 individual plants. In this population, 4 % of the plants produce red flowers, and 9 % produce pink flowers. The remaining plants produce white flowers. Flower colour is attributed to a single locus with two alleles. Red flowers are produced by plants that are homozygote for the R allele. White flowers are produced by plants that are homozygote for the W allele. Heterozygotes (RW) produce pink flowers. What is the expected (under Hardy-Weinberg equilibrium) number plants producing pink flowers in this population? Round your answer to the closest full number.
Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
