Paulina is an 18 year old young woman who has a preoccupation with her nose. She is convinced it is too large for her face. She spends at least an hour every morning applying make up to create the illusion of a smaller nose and then she spends several more hours looking at her nose in the mirror, and is constantly asking her friends if her nose is too big. Her friends reassure her that her nose is a normal size and that she is pretty. She wishes she could save enough to have plastic surgery, as her parents refuse to pay for it. She is so convinced her nose is hideous that she doesn't enjoy meeting new people and is slowly slipping into a state of depression. It is likely that Paulina has this disorder:

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
