A horticulturalist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed by the allele R(RR and Rr) and the trait of white flowers is governed by the allele r(rr).

The horticulturalist plans to cross a geranium that is true-breeding for red flowers with a geranium that is true-breeding for white flowers.

Which Punnett square best describes this cross?

R RR Rr
r Rr rr

Birth and Death rate table. In year 0, birth rate is 0.25 and death rate is 0.5. In year 1, birth rate is 0.3 and death rate is 0.4. In year 2, birth rate is 0.4 and death rate is 0.2. In year 3, birth rate is 0.5 and death rate is 0.15. In year 4, birth rate is 0.5 and death rate is 0.2. In year 5, birth rate is 0.4 and death rate is 0.3.

Illustration of food web including a relationship between green plants, a mouse, a rabbit, a goat, an owl, a snake, a wild cat, a jackal, a kite, and a lion.

Four graphs A, B, C and D. Each graph is a line that occupies a square. The left and right sides of the graph touch the x axis. Each graph has a different shape, but the space under the line remains the same. Graph A. Solid line symmetrical bell-shaped curve. Graph B. Dotted line symmetrical bell-shaped curve superimposed on a solid asymmetrical curve that leans to the right of the dotted curve. Graph C. Dotted line symmetrical bell-shaped curve superimposed on a solid curve. The solid curve is symmetrical. It goes up on both ends to form two humps and it is lower in the middle. The solid curve looks like the letter M. Graph D. Dotted line symmetrical bell-shaped curve superimposed on a symmetrical curve that is narrower and taller than the dotted line curve.

Tree diagram with five levels, showing genetics of Darwin finches. Starting from bottom, level one shows Common ancestor from South American mainland. Level two shows Ground, Tree, and Warbler finches with their Genuses as Geospiza, Camarhynchus, and Certhidea respectively. Level three shows Seed eaters, Sharp-beaked ground finch or G difficilis, Cactus flower eaters, Bud eater, and Insect eaters. Level four shows Large ground finch or G magnirostris, Small ground finch or G fuliginosa, Cactus ground finch or G scandens, Small tree finch or C parvulus, Medium tree finch or C pauper, and Woodpecker finch or C pallidus. Level five shows Medium ground finch or G fortis, Large cactus ground finch or G conirostris, Vegetarian finch or C crassirostris, Large tree finch or C psittacula, Mangrove finch or C heliobates, Green warbler finch or Certhidea olivacea, and Gray warbler finch or Certhidea fusca.
