1. Chargaff's experiments in DNA analysis were consistent in which respect no matter what organism was studied?
A. The percentages of adenine (A) and thymine (T) were
always equal.
B. The percentages of guanine (G) and thymine (T) were
always equal.
C. The percentages of adenine (A) and guanine (G) were
always equal.
D. The percentages of thymine (T) and cytosine (C) were
always equal.

Which step if the scientific method relies more heavily on newly collected data than on creativity and innovation

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
