The Rainbow Connection
The genetic variability or the Giddings children started out as mutations that occurred thousands of years ago. Take hair color: Our distant ancestors probably all had dark hair, its color controlled by multiple genes located on several different chromosomes. The alleles that produced Tess's blond hair originated as mutations in genes that control the amount and type of hair pigment. Tess probably inherited only “pale hair” alleles of all of these genes, so for any given hair color gene, she has the same pale hair allele on both homologous chromosomes. Chris, on the other hand, inherited both dark and pale hair alleles for at least some of the genes, so his homologues have different alleles. As we will see in Chapter 11, in many cases one allele (in this case, the dark hair allele) overrides the effects of the other allele (the pale hair allele), so Chris has black hair. What combinations of alleles might have been packaged in Tess's eggs and Chris's sperm, which would combine to produce their diverse children?

Certainly, not all Muppets look like the one shown in the picture below, nor do they all look the same. In fact, there’s a great deal of phenotypic variation in Muppets. Two traits that have been particularly well-studied are curly hair presences and skin color.
One individual is a male, and he possesses a green skin and no hair, whereas the female individual possess a curly hair and pink skin. Let’s call the gene controlling skin coloration S and that controlling hair H. In this species, both hair and green skin are recessive traits. Both of the individuals shown are homozygous.

Eye colors are passed down through generations, but sometimes genetic variations can lead to surprising results in eye colors (dark eye color, still rocks!?) Some examples are found below.
Is there truth behind the following? Provide explanations for your answer.
Two parents with blue eyes cannot have a brown-eyed child and vice-versa.
Eyes with more than one color stems from parents with two different eye colors.
People with violet eyes are mutants.
People with red or pinkish eye color can have dark-eyed parents.
The zebra fish is a very popular aquarium pet fish that is known to be hardy, attractive, and able to survive well in groups. Wild type zebra fish have blue–purple horizontal stripes that run from gill to tail, with a silver–gold body.
An alternative form of the zebra fish results from a mutation that causes a homozygous recessive red-colour fish.
Could you kindly answer all of the questions? It's multiple choice so minimal explanation is needed and i do not have a lot of questions left. Thank you.

- ONE OF THE ANSWER IS WRONG PLEASE HELP ME FIND THE RIGHT ANSWER Duplication of genes is an important evolutionary mechanism. As a result, many, cases are known in which a species has two or more identical genes. Suppose there are two genes - A and B - that specify production of the same enzyme. These two genes show autosomal recessive inheritance. An abnormal phenotype results only if an individual does not make any of that enzyme. Only one of these two genes needs to be functional in order to make the enzyme. What ratio of normal to abnormal progeny would result from a mating between two parents of genotype AaBb where A and B represent alleles that specify production of the enzyme, while a and b do not? Write your ratio like this - e.g 1:2 ratio - Suppose now there are three genes - A,B and C that specify production of this enzyme and again only one single functional allele is sufficient for a wild-type phenotype. How many of the possible phenotypes would be normal? Write your answer…arrow_forwardAlbinism in animals is caused by recessive mutations inone of several autosomal genes required for synthesis ofmelanin, a chemical precursor for many skin and eye pigments. Albino animals are often confused with so-calledleucistic animals that are white due to recessive mutationsin a gene required in a different pathway, for example apathway for development of the cells that produce all skinpigments. Suppose you have two white hummingbirds—a male and female—and they have mated. Assuming thatall relevant mutations are rare, autosomal, and recessiveto wild-type alleles, what would you expect their progenyto look like under the following conditions:a. They are both albinos.b. They are both leucistic.c. One is albino and the other is leucistic.arrow_forwardTo understand this research, you must be familiar with some basic genetic terminology.

- Albinism is a recessive trait in humans.A geneticist studies a series of families in which both parents have normal pigmentation and at least one child has albinism. The geneticist reasons that both parents in these families must be heterozygotes and that albinism should appear in 14 of their children. To his surprise, the geneticist finds that the frequency of albinism among the children of these families is significantly greater than 14. Can you think of an explanation for the higher-than-expected frequency of albinism among these families?arrow_forwardAlbinism is a recessive trait in humans .

- Drosophila can have 1, 2, or 3 stripes on their body. From previous experiments, you suspect that there are 2 genes (Gene C and Gene D) that control the number of stripes. A recent published paper described a similar stripe pattern in bees. Furthermore, in bees, Gene C is recessively epistatic to Gene D, are on different chromosomes, and the order of function is the following: C D 3 stripes → 2 stripes 1 stripe You therefore set out to test the hypothesis that Gene Cis also recessively epistatic to Gene D in Drosophila. To do so, you begin by crossing pure breeding 1-striped drosophila with pure breeding 3-stripped drosophila. To statically test your hypothesis, you proceed to perform a chi-square analysis on data obtained from the F1 X F1 cross. Using your hypothesis as your basis to analyze the results, fill the table below. Note: You do not have to calculate the chi-square or make a conclusion. Just fill the table.

(Recall that not all SNPs affect phenotype.)arrow_forwardA scientist investigating the genome of two related individuals observes a difference of a few nucleotides in one individual compared to the other. The nucleotide differences are in a region of noncoding DNA on chromosome 1. Would these differences be considered a mutation? Why or why not? Yes, the difference in nucleotide sequences between the individuals is a mutation because it will affect the phenotype of the two individuals. Yes, any heritable variation in the nucleotide sequence is considered a mutation, even if that variation is in a noncoding region of DNA. Not enough information was provided to determine if this nucleotide difference is a mutation because the effect on phenotype is unknown. No, the change in nucleotide sequence doesn't appear in a coding region of the DNA and so can't be a mutation.arrow_forward

It must bounce continuously or it will die. Imagine that the spring in the tail is controlled by a single gene with two alleles T and t. Individuals with the genotype TT have very stiff tails that take a lot of energy to bounce, Tt have just the right amount of spring, and those with tt tails have very floppy tails that deform after long periods of bouncing, making it very difficult to continue bouncing. The genotype frequency in this population is: TT=25% Tt=70% tt=5% Part A: The frequency of the t allele in the population is ___%. The expected frequency of the Tt genotype in the population is ___%.
