The ________ is the one most commonly found in nature.

In guinea pigs, black color is dominant to brown color and smooth fur is dominant to curly fur.  A guinea pig that is heterozygous for fur color and texture mates with another guinea pig heterozygous for both traits.  If they produce a total of 100 offspring, how many of those offspring would you expect to be black and smooth?

True or false.  A single mutation in any regulatory gene causes cancer.

Gregor Mendel made four important postulates that explained his observations and laid the foundation for our understanding of genetics.  We now know that Mendel’s postulates make several assumptions that do not always hold true.  These assumptions include: Each gene has only 2 alleles There is always a clear dominant-recessive relationship between traits Each trait is controlled by a single gene Mendel’s law of independent assortment assumed that one trait has no effect on the inheritance of another  Provide one example from the trait that you researched for your pedigree project where one of these assumptions does not hold true.

A red flowering plant is crossed with a white flowering plant.  All of the offspring are pink flowering plants.  This pattern of inheritance is an example of

If an individual has the genotype BbCc, list all of the unique gametes that individual can produce.

1. (1)Jargon—a specialized vocabulary used by a particular group, such as lawyers, teenagers, or musicians—has several benefits for group members. (2)One benefit of jargon is that it provides a way of setting insiders apart from outsiders because only the insiders know what it means.

3. Read the paragraph below. Which sentence gives the main idea?  1. (1)Most non-human mammals demonstrate only a passing interest in the dead of their own species. (2)Lions will generally sniff or lick another dead lion before beginning to eat the body; chimpanzees will try to interact with their dead friends and relatives only until their bodies start to decompose. (3)Elephants, however, are unique among non-human mammals in that they appear to actually mourn their dead. (4)When presented with the dead body of another elephant, elephants will generally become agitated and upset, and caress the carcass with their trunks and feet. (5)In experiments in which elephants have been shown the skulls of a rhinoceros, a buffalo, and another elephant, they have demonstrated interest in only the elephant skull, gently touching and investigating it with their trunks and feet in much the same way they would a fellow elephant. (6)They also appear to be able to distinguish even very small pieces of ivory (elephant tusk) from other substances such as wood and rocks, for when presented with all three substances, elephants are overwhelmingly drawn to, and become agitated over, the ivory. (7)Animal scientists interpret these patterns of behavior as evidence that elephants are in mourning. Which sentence gives the main idea?
