In a population with brown and green alleles for color, genetic drift View Available Hint(s) In a population with brown and green alleles for color, genetic drift has more effect on the evolution of a small population. occurs when individuals move into or out of a population, changing the allele frequencies in the population. causes populations to become better adapted to their environments. has more effect on the evolution of a large population. always increases the frequency of brown alleles in the population.

Methane gas created by a cows flatulence especially in a large herd is a greenhouse gas. true or false.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
