Genetics and Evolution

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

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

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 —

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

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

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?

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?

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?
