In squash plants, yellow fruit (Y) is dominant to white fruit (y). If two plants heterozygous for yellow fruit are crossed, what are the possible genotypes of the offspring?

After a culture of cells is allowed to multiply and is viewed through a microscope, the cells are x-rayed with high-energy radiation for less than 1/100th of a second. After the radiation, many newly reproduced cells appear different. What happened?

Which of the following is an example of a genetically engineered organism?

Wild cats such as cheetahs, lions, and tigers experience decreased genetic diversity as their populations decline and become fragmented due to habitat destruction. Decreased genetic diversity leads to populations with

People who have been exposed to excessive radiation often experience mutations. If these mutations only occur in somatic (body) cells, these people may —

In cows, long hair is dominant to short hair. In a cow that is heterozygous for long hair, what percentage of the cells undergoing meiosis will carry the dominant allele?

In rabbits, short fur (F) is dominant to long fur (f). According to the Punnett square, what is the chance of two heterozygous short-haired rabbits having offspring with short fur?

Which of the following statements describes the process of natural selection?

DNA that is derived from the DNA of two or more different species is called —

Lamarck was an early scientist who studied the development of characteristics in organisms over time. Which of the following choices best describes his views on how organisms change over time?

A genetic pedigree showing that only males are affected by a certain disorder is evidence of what type of inheritance?

The chances of developing cancer, diabetes, or sickle-cell anemia are higher if a family member also has the disorder because they are —

Over many generations, unrelated or distantly related species may come to resemble each other due to —

External sources, such as radiation or chemicals, can cause mutations in genes or entire chromosomes. For a mutation to pass on to offspring, it must occur in a —
