In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). This change in skin color provides evidence that - A ultraviolet light can cause mutations. B the environment can influence gene expression. C the inheritance of skin color is an acquired characteristic. D albinism is a recessive characteristic.

Which statement best describes the given diagram? A Only the fertilized egg contains DNA and the tissue cells do not. B Heart, brain, and lung cells are the only types of cells fertilized eggs produce. C Cells in fertilized eggs are directed by DNA to become many types of cells. D The DNA in fertilized eggs are different than that of cells of organs.

Which of the following describes the role of RNA in cell differentiation? A The RNA determines the type of DNA that will be made. B The RNA assembles the proteins that are made in a specific type of cell. C Each cell has a different set of DNA and RNA that determines cell type. D RNA has nothing to do with cell differentiation.

The color of fruit for plant "R" is determined by two alleles. When two plants with orange fruits are crossed the following phenotypic ratios are present in the offspring: 25% red fruit, 50% orange fruit, 25% yellow fruit. What are the genotypes of the parent orange-fruited plants? This is an example of what type of inheritance?

A cross between a black cat & a tan cat produces a tabby pattern (black & tan fur together). What pattern of inheritance does this illustrate? What percent of kittens would have tan fur if a tabby cat is crossed with a black cat?

Kanye and Kim are having a baby. Kanye’s genotype is IᴮIᴮ. Kim’s genotype is ii. What are the possible options for the baby’s blood type?

Hairy ears are an x-linked recessive trait in humans. If you mate a homozygous hairy ear female with a normal male: What are the expected offspring genotypes and phenotypes and their ratios? What does a female’s genotype have to be in order to express the disease? What does a female’s genotype have to be in order to be a carrier of the disease? What does a males’ genotype have to be in order to express the disease? Can a male be a carrier of an X-linked recessive trait?

Hemophilia has played an important role in Europe’s history, for it suddenly cropped up in the children of Great Britain’s Queen Victoria. It became known as the “Royal disease” because it spread to the royal families of Europe through Victoria’s descendants. One of her descendants, Alice of Athlone, had one hemophilic son (Rupert) and two other children—a boy and a girl—whose status is unknown. What is the probability that her other son was hemophiliac?

Where is the chromosomal abnormality in the above karyotype? What occurred during meiosis that would have caused this abnormality?

Nondisjunction – Homologous chromosomes Not separating in meiosis

Describe two processes that occur during meiosis that increase genetic variation? How would the DNA fingerprints of identical twins compare to that of fraternal twins? Where does a mutation have to occur in order for it to be inherited by the offspring?

Homologous Structures St Analogous Structures Which of the above structures is evidence of adaptative radiation? Which of the above structures is evidence of convergent evolution? Vestigial Structures
