What is the GENOTYPE ratio of the following offspring? * T TT Tt Tt tt O 3 Tall: 1 Short 3 TT: 1 tt 3 Short: 1 Tall O 1 TT: 2 Tt: 1 tRefer to the pedignee below for this question, Individuals who are shaded have a rare autosamal recessive disorder. Those who are not shaded have the dominant phenotype. Let "A" and "a' represent the dominant and recessive alleles, respectively. Fill in the probability functions below to indicate the genotype or probability function far the genotype of each individual. Give all probabilities as fractions that are simplified to the lowest value. Type your fractione in ## format without spaces. For axample, one-half should be typed as 1/2.

- 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 2For each of the genotypes below determine what phenotypes would be possible. Purple flowers are dominant to white flowers Bobtails in cats are recessive PP TT Pp Tt Pp tt Brown eyes are dominant to blue eyes Round seeds are dominant to wrinkled seeds BB RR Bb Rr Bb rrA gene has two alleles, E and e. Another gene also has two alleles, T and t. Which of the following correctly shows linkage between the two genes? Group of answer choices ET/et Te/Et Ete/T Ee/tT
