- In a population of 1000 individuals, 150 have kinky hair, 460 have wavy hairy, and the rest have straight hair. Let us assume that hair type is governed by a pair of alleles, and there are two types of alleles, S (kinky) and s (straight), with the heterozygote condition being wavy. Compute for the allelic frequencies for hair type in the population.Most of the individuals of a certain wildflower population have yellow flowers, although a few are white-flowered. Crosses have demonstrated that allele for yellow flower (Y) is dominant over the allele for white (y). If two heterozygous yellow-flowered plants are crossed, what fraction of the offspring do you expect to be white? Show your solution.A cross is made between AA Bb Cc Dd and Aa Bb cc dd individuals. Rather than making a very large Punnett square, which statistical operation could you use to solve this problem, and whatwould be the probability of an offspring that is AA bb Cc dd?a. Product rule, 1/32b. Product rule, 1/4c. Binomial expansion, 1/32d. Binomial expansion, 1/4
- Most of the individuals of a certain wildflower population have yellow flowers, although a few are white-flowered. Crosses have demonstrated that allele for yellow flower (Y) is dominant over the allele for white (y). If two white flowered plants are crossed, what fraction of their offspring do you expect to be YELLOW? Show your solution with punnet squareIn a population of beans that is mostly diploid, there are an assortment of them: black, white, orange, red, green, fuchsia, brown, yellow. Determine the number of alleles that can be observed in the bean population?The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each.
- In a population of beans that is mostly diploid, there are an assortment of them: black, white, orange, red, green, fuchsia, brown, yellow. What is the maximum number of alleles present in one bean?Most of the individuals of a certain wildflower population have yellow flowers, although a few are white-flowered. Crosses have demonstrated that allele for yellow flower (Y) is dominant over the allele for white (y). If two white flowered plants are crossed, what fraction of their offspring do you expect to be yellow? Show your solution.In Andalusian fowls, black (BB) and white (bb) individuals are homozygous. When a homozygous black bird (BB) is crossed with a homozygous white (bb) bird offspring are all bluish-gray (Bb).

- In some breeds of chickens, there are alleles for black color and white color. Neither of these alleles is dominant over the other. When a chicken of one of these breeds has both of these alleles, its color is black-and-white spotted (which is also called erminette). If a spotted chicken is bred with a black chicken, the phenotypes of the offspring will occur in what ratio? (Hint: Construct a Punnett square to help you answer this question.) A 1:2:1 ratio of black, spotted, and white A 1:1 ratio of spotted and white A 1:1 ratio of black and spotted A 1:3 ratio of white and black In these breeds of chickens, the alleles for color are an example of codominance or imcomplete dominance? In one species of finch, there are alleles for yellow color and red color, but neither of these alleles is dominant over the other. When a finch of this species has both of these alleles, its color is orange. If an orange finch is bred with a yellow finch, the…n a container/tub, place 50 pieces ofred paper, 50 pieces of pink paper, and50 pieces of white paper. Let usassume that each color is thephenotypic expression of thegenotypes homozygous dominant AA(red), heterozygous Aa (pink), andhomozygous recessive aa (white).Without looking, randomly pick 20 pieces of paper from your container/tub and assumethat those individuals died upon picking, thus will be removed from your population. a. If you are a picky eater and prefer the white only, what do you think will happen in the genotypic frequency and allelic frequencies of the red, pink and white pieces of papers?In dogs, black fur (B) is dominant to brown fur (b). In a genetic cross of two dogs that are heterozygous for the color of their fur, what is the genotype and the phenotypic ratio of the offspring? A)F: Bb, Bb, bb; ratio 2;1B)F: BB, bb; ratio 1:1C)F: Bb, bb, bb; ratio 1:1D)F: BB, Bb, Bb, bb; ratio 3:1E) F: BB, Bb; no ratio
