Flower diameter in sunflowers is a quantitative trait. Each upper case allele provides a fixed amount of cm additional in diameter. Each lower case provides a different fixed amount of cm additional in diameter. A plant with 8-cm flowers and aabb genotype is crossed to a plant with 16-cm flowers and a AABB. What is the probability of of getting a 16cm flower in F2? 1/8

What is the difference between incomplete dominance and codominance? * a. The dominant allele completely masks the recessive allele. b. In codominant traits, both alleles are expressed, while incompletely dominant traits mix to create a third phenotype c.

Introduction: A dihybrid cross is a cross between individuals that involves two pairs of contrasting traits. To Predict the results of a dihybrid, cross all possible combinations of the four alleles from each parent must be considered. You will examine a dihybrid cross involving both color and texture. Purple (P), is dominate to yellow (p), and smooth texture (S) is dominant to wrinkled (s). Both parent plants are heterozygous for both traits. Review genetics and the use of Punnett squares in a biology text before doing this experiment.MATERIALS: Assume you have ear of Corn. You need a heterozygous X heterozygous 9:3:3:1, purple/yellow, starchy/sweet.
