Draw a punnett square for each problem. Please be careful to notice whether a trait is homozygous or heterozygous. In rabbits it has been shown that albino (white) is recessive to the brown color, such as in the wild rabbit. If a homozygous albino rabbit and a homozygous brown rabbit are bred, what will be the color ratio of the first generation? Answer:___________brown _____________tan______________white 2. If a pure (homozygous) white guinea pig is bred with a hybrid (heterozygous) black guinea pig, what would be the probable color ratio of the next generation? Black is dominant. White is recessive. Answer:___________black _____________gray _____________white Thank you.

Relationship between IA and IB Relationship between IB and i Incomplete dominance Codominance b. Relationship between IA and IB Relationship between IB and i Multiple alleles Incomplete dominance c.

Describe the two possible versions of the traits for all of the characteristics you found in Pod shape, Pod color, Pea shape, Pea color, Flower color, Position of the flower. Give the ratio of the traits in the F2 generation for each (Mendel actual ratio). List the trait that was considered dominant first and the recessive trait second, for each pair of traits. Show the shorthand code for each trait. See the example below for plant height to see an example of how you can write your answer. Make sure your answer includes all six of the other historical ratios besides plant height. Example: Plant Height = 3 Tall (T) for every 1 short (t) plant = 3 T:1 t (Note: more precisely, Mendel’s result was 2.84 T:1 t).
what will be the The chance of Susie and Fred having a kitten that is heterozygous for the trait of nose color is? and what will be the The chance of Susie and Fred having a kitten that has a pink nose is? and what will be the The chance of Susie and Fred having a kitten that is homozygous (dominant OR recessive) for the trait of nose color is:
Show the complete solution including the Punnett Sq. Lina has dimples, freckles, and a widow’s peak. She is a heterozygous for all of the three traits. David, her husband also has freckles and dimples but has a continuous hairline. As freckle is known to be dominant over none, dimples are dominant over no dimples, and widow’s peak is dominant over continuous hairline, identify the Probability that their child will have three recessiveness: no freckle, no dimples, and has widow’s peak; and Probability that their child will have the same phenotype as Lina (with freckles, dimples, and widow’s peak). Legend: Ff – freckles Dd – dimples Ww – widow’s peak
Draw a punnett square for each problem. Please be careful to notice whether a trait is homozygous or heterozygous. One parent has O type blood. The other parent has heterozygous B type blood. What are all the possible blood types the children may have? Answer:____________O ____________A _____________B _____________AB In a paternity case a man is accused of having fathered a child. He denies the accusation and presents the following evidence. His blood is O. The mother’s type is AB. The child has AB blood. Could he be the father? _______yes ________no
Capital, upper-case H represents a Hornet with a dominant stinger capable of delivering a strong venom and lower-case h represents a recessive stinger that does not deliver a strong venom. In fact, the venom delivered by a recessive stinger is 1% potent. The venom of the H trait is 100% potent. Cross a HH Hornet with a Hh Hornet. Using a Punnett Square, what is the percentage of hornets from this cross showing a dominant stinger as a PHENOTYPE? Cross a heterozygous male and female Hornet for the Stinger Trait. So, Cross Hh with a Hh. Using a Punnett Square, what is the percentage of hornets from this cross showing a dominant stinger as a PHENOTYPE? Using a Punnett Square, what is the percentage of hornets from this cross showing a recessive stinger as a PHENOTYPE?
An individual with a form of red-green color blindness processes a genetically inherited trait that makes it difficult to distinguish red and green color hues. Red-green color blindness tends to skin generations and it is found much more often in men than in women. If a man who was normal and a woman who is a carrier for this form of colorblindness have a child, when the probability that the child will be red-green colorbind is: -0% -25% -50% -75% -100%
A one-eyed flying people-eater usually has purple skin. One-eyed flying people-eaters who are recessive for skin color are albino. A heterozygous purple one-eyed people-eater has offspring with an albino female one-eyed people-eater. Value: 1 Which of the following are the genotypes of the parents? (select one for each parent.) [mark all correct answers] a. Father - PP b. Father - Pp c. Father - pp d. Mother - PP e. Mother - Pp f. Mother - pp g. Not enough information is given to determine the father's genotype. h. Not enough information is given to determine the mother's genotype.
A tall pea plant (homozygous dominant) is crossed to a pea plant that is heterozygous for the gene for height. Create a Punnett Square and use it to answer the following questions: What is the genotypic ratio of the offspring? What is the phenotypic ratio of the offspring? Answers are written as genotype; phenotype a) 50% TT : 50% Tt; 100% tall plants b) 1 TT : 2 Tt : 1tt; 75% tall plants : 25% dwarf plants c) 1 TT : 2 Tt : 1tt; 25% tall plants : 50% medium height plants : 25% dwarf plants
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Draw a pedigree chart for the family described below and use the chart to determine the genotype or possible genotypes of each member of the family. Be sure to define your variables. In humans, having freckles is dominant over not having them. Both Mr. And Mrs. Chambers have freckles. Of their three children, Robin and Daniel have freckles but Alex does not. Robin marries Stephen, who does not have freckles. They have two children, Kevin and Beth, who do not have freckles. Daniel marries Diane who also has freckles. They have one son, Phillip, who also has freckles. Alex marries Mary, who has freckles. They have one daughter, Norma, who does not have freckles.
Using the pedigree below, determine whether the alleles B or C have a dominant or recessive relationship, which allele is dominant, and the genotype for individuals I-1, I-2, I-3, I-4, II-4, and II-5. Use B or C for the alleles and X for unknown alleles. Note: White squares/circle indicate normal phenotypes. Dark squares/circles indicate the individual has the condition. The B allele is associated with the condition. Label the pedigree chart with genotypes as needed.
