- Eye Color is a trait that involves a number of genes. To simplify our example, we can break down the traitinto two phenotypes: dark color and light color eyes. Dark coloration is considered dominant, or isexpressed in a heterozygous condition (when the alleles are different).Q: If you have one light eyed parent and one parent that is homozygous for dark eye color, what are thepotential eye colors of their offspring (young)? To start, what do the Parents’ alleles look like? What istheir Genotype? (Remember, you pick which letter you want to use)Light eye colored parent:Dark eye colored parent:One of the things Mendel designed was a way to provide information about how the genes are passed onfrom parent to offspring. He designed something called a Punnett Square. This square places the parents’alleles outside the box, then uses those alleles to fill in the squares.Let’s start with a reminder of what we know about the parents: Parent Phenotype(appearance) Genotype(alleles) 1 2Consider the following cross examining four gene in two parental line: Parent 1: A/a; B/B; D/d; E/e Parent 2: A/a; B/b; d/d; e/e Assuming independent assortment for the four genes, what fraction of progeny will be phenotypically identical to either parent 1 or parent 2? (Hint: first figure out the fraction of progeny that resembles parent 1 and parent 2 separately, then get the overall fraction.) 9/16 1/16 3/4 3/8 3/16Get the genotypic and phenotypic ratio of the following: Dihybrid cross: Harry has 1 pair of dog, he’s going to breed his Pure black, furry male to his white furless female (P generation). Also, he wants to find out what will be the result if he breed 2 offspring from F1 generation. Help him to predict the P and G ratio of F1 and F2 generation using the Punnett Square. Dominant Recessive Black White Furry Furless Trihybrid cross: Breed AaBbCc to another AaBbCc.
- Imagine you have a blood group of "X" which is recessive and expressed by xx. The dominant blood groups are Y and Z, where homozygous of these alleles are expressed as YY and ZZ, respectively. What will be the genotype of your parents blood group? Why? Please explain in your own words. [Max 200 words]A particular species of flowering plant comes in three colors: Red, Blue, and Purple. Red is considered homozygous dominant, blue is considered homozygous recessive, and purple is considered heterozygous. Please use F to represent dominant alleles and f to represent recessive alleles. A member of this plant species that makes red flowers cross-pollinates with a member of the same species that makes blue flowers. In your answer, please state the mode of inheritance, the genotypes of both parents, and the genotypic and phenotypic ratios of the offspring.In domestic cats, the dominant allele A encodes pigmented fur and the recessive allele a encodes white fur. Two cats with Aa genotypes have a litter of kittens. For each kitten, what is the probability that the kitten has pigmented fur? Hint: it may be helpful to draw a Punnett square.
- In rabbits, an allelic series helps to determine coat color: C (full color), cch (chinchilla; gray color), ch (Himalayan; white with black extremities), and c (albino; all white). The C allele is dominant to all others, cch is dominant to ch and c, ch is dominant to c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C > cch > ch > c. Indicate the phenotypic ratios expected in rabbits with the cross cchch × chc. 1 full color:1 chinchilla 1 full color:1 Himalayan 1 chinchilla:1 Himalayan 3 full color:1 chinchilla 2 full color:1 Himalayan:1 albinoConsider three independently assorting gene pairs, A/a, B/b, andC/c, where each demonstrates typical dominance (A9, B9, C9)and recessiveness (aa, bb, cc). What is the probability of obtainingan offspring that is AABbCc from parents that are AaBbCC andAABbCc?For each gentype below indicate whether it is heterozygous (he)or homozygous (ho)
