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
The dominant C allele of a gene that controls color in corn produces kernels with color; plants homozygous for a recessive c allele of this gene have colorless or white kernels. What kinds of gametes, and in what proportions, would be produced by the plants in the following crosses? What seed color, and in what proportions, would be expected in the offspring of the crosses? a. CCCc b. Cccc c. CcCc
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.
Two pairs of traits are segregating in a cross. Two parents produce 156 progeny that fall into 4 phenotypes. The numbers of offspring in the 4 phenotypes are 89, 31, 28, and 8. What are the genotypes of the two parents?
1. If your genotype is Bb, what type of trait would you express as phenotype? a. dominant b. recessive c. both a and b d. neither a nor b 2. If your genotype is BB, what type of trait would you express as phenotype? a. dominant b. recessive c. both a and b d. neither a nor b 3. If a baby goat received a dominant gene for curly hair from one parent, and a recessive gene for straight hair from the other, which trait will the baby goat display? a. No hair b. Curly hair c. Straight hair d. Straight and curly hair 4. The allele for yellow seeds in pea plants, Y, is dominant. The allele for green seeds in pea plants, y, is recessive. Which combination would produce a plant with green seeds? a. YY b. Yy c. yY d. yy 5. In humans, the allele for brown eyes, B, is dominant over the allele for blue eyes, b.

1. If a purebred pea plant with purple flowers was crossed with a purebred pea plant with white flowers, all of the offspring's flowers ended up being purple. In this instancethe WHITE flower trait is considered to be what?
2) A researcher crossed a heterozygous yellow seed plant (Yy) and a recessive green seedplant (yy). Draw a Punnett Square and determine the genotype and phenotype ratios ofthe offspring.
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
