Which of the following represents an example of qualitative phenotypic variation? a. the lengths of peoples toes b. the body sizes of pigeons c. human ABO blood types d. the birth weights of humans e. the number of leaves on oak trees
In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds

4) A testcross is used to determine which of the following? a) The phenotype of an individual with a dominant genotype b) The phenotype of an individual with a recessive genotype c)The genotype of an individual with a dominant phenotype d) The genotype of an individual with a recessive phenotype
3. A wild flower has a dominant allele of red-flower color which is incompletely dominant over the allele of white-flower color. Draw the Punnett square for the cross. Identify the flower color phenotypes and theoritical percentage.
2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
7. The ability to roll your tongue (R) is dominant to lack of this ability (r). A. What is the genotype of a man who can roll his tongue if his father couldn’t? B. If a man who is heterozygous for tongue rolling marries a woman who is heterozygous, what would you predict for the genotypes and phenotypes of their children?
1)If both parents are heterozygous, which genotypes are possible for their offspring? choose all that apply A)homozygous dominant B)heterozygous C)homozygous recessive D)more information would be needed
