From the data,
a. Calculate the population of Gilder for each 10-year period by filling in the Population (NO) and Population (Nt) columns in the data table. Use this formula to do your calculations:
Population size:
Nt = No + (B + I) – (D + E)
initial population = 20,000,000
b. Which of the following might reasonably explain the change in Gilder’s population? Explain your choice of answer(s).
• prosperous economy only
• improved health care only
• prosperous economy along with improved health care
• neither a prosperous economy nor improved health care

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
