In four-o'-clock plants, the allele for red flowers is incompletely dominant to the allele for white flowers, so heterozygotes have pink flowers.  What ratios of flower colors would you expect among the offspring of white flower plants X pink flower plants.

using a Punnett square, what will the offspring look like when the parents are Bb and Bb. B = dominant black hair and b = recessive blue hair. So what percentage of the offspring will have black hair vs blue hair?

Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. Trait Dominant Recessive Pod color Yellow Green Pea shape Round Wrinkled A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? a) 1/2 b) 1/4 c) 1/8 d) 1/16

In swallowtail butterflies, let's pretend that the R gene codes for coloring on the forewing. The R1 allele, which codes for red color, is dominant to the R2 allele, which codes for white color. If R1 is a recessive lethal allele, what phenotypic ratio would you expect when crossing two swallowtails with red forewings?  1 red : 2 white  1 red : 3 white  3 red : 1 white  there is not enough information given to answer this question  1 red : 1 white  2 red : 1 white
