Some inbred strains of the weedy plant arabidopsis thaliana flower early in the growing season, but other strains flower at later times. four different arabdiposis plants (1–4) were crossed, and the resulting progeny were tabulated as follows: mating progeny 1 × 2 77 late : 81 early 1 × 3 134 late 1 × 4 93 late : 32 early 2 × 3 111 late 2 × 4 65 late : 61 early 3 × 4 126 late a. explain the genetic basis for the difference in flowering time. how do you know that among this group of plants, the flowering time trait is influenced by the action of a single gene? which allele is dominant and which recessive? b. ascribe genotypes to the four plants. c. what kinds of progeny would you expect if you allowed plants 1–4 to self-fertilize, and in what ratios?

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
