True or False: . Evolution happens because organisms need new features.

. Traits cannot be good or bad, their effect on the success of a creature depends on the environment and circumstances.

. A mutation in an individual is evolution.

. The process of evolution is random, but the selection of genes/traits is not.

. An organism that is more complex is more evolved.

. Only creatures that look similar share a common ancestor.

. “Survival of the fittest” means that the strongest, fastest, fiercest individuals are the ones
that get to reproduce.

. Except for differences between male and female, all individuals in a population are genetically the same.

. Nature is selecting for some traits and against other traits all the time.

. Evolution is a theory that is strongly supported by multiple lines of evidence from multiple fields of study.

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
