Joe has a white cat named Sam. When Joe crosses Sam with a black cat, he obtains 1⁄2 white kittens and 1⁄2 black kittens. When the black kittens are interbred, all the kittens that they produce are black. On the basis of these results, which coat color (white or black) in cats would you conclude is a recessive trait? Explain your reasoning and provide your Punnett square.

) Joe has a white cat named Sam. When Joe crosses Sam with a black cat, he obtains one-half white kittens and one-half black kittens. When the black kittens are interbred, all the kittens that they produce are black. On the basis of these results, would you conclude that white or black coat color in cats is a recessive trait? Explain your reasoning.
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
Assume that one of the students in your class is homozygous for the “Type A” allele and the other student is homozygous for the “Type B” allele. What blood type(s) would you expect to see in their offspring? What if the second was instead “Type O”? Cross two individuals who both have Type AB blood. What are the expected genotypic and phenotypic ratios in their offspring?
A man who is red-green color-blind marries a woman who is neither color-blind nor a carrier for this trait. Which statement would best describe their probable offspring?
Albinism is the absence of pigment throughout the body. Animals with albinism have white fur and reddish eyes. Albinism is inherited as a recessive trait, so animals with two a alleles have albinism, whereas animals with at least one dominant A allele have normal coloring. Using the Punnett square below, determine the probability of two albino parents (with aa genotypes) producing a child with albinism.
In humans brown eye color is dominant to blue eye color. Suppose that your mother is homozygous and your father is heterozygous and you have brown eyes. If you have a child with blue eyes, what are the possible genotypes of both of your parents? Group of answer choices Mother bb; Father bb Mother BB; Father BB Mother BB or bb; Father Bb Mother Bb ; Father Bb
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? A - 1/2B - 1/4C - 1/8D - 1/16
Give an example of a family tree that shows the F^1 generation and F^2 generations of your mother and father side with dominant traits.
In this family tree, individuals with the trait are shown in black. Circles represent biological females. Squares represent biological males. Is the trait dominant or recessive? Explain your answer. Is the trait sex-linked? Explain your answer.
Use the following parents to create a Punnet Square and answer the question. Cross a heterozygous father with a homozygous recessive mother. (you can use the letter A for your parental genotypes) What percent of the offspring will be homozygous recessive?
If black fur color is controlled by a dominant allele (B) and brown by its recessive allele (b), give the genotypes of the parents and offspring of a cross of a black male with a brown female that produces 1/2 black offspring and 1/2 brown offspring.
The pedigree below represents which individuals in a given family have attached earlobes. Unattached earlobes are dominant over attached earlobes.Which of the following statements is true of the pedigree? a Individuals 8 and 9 are heterozygous for the trait. b Individuals 1, 2, 3, and 4 have attached earlobes. c Individuals 6, 7, and 10 are male. d Individuals 11 and 12 are identical twins
