Chapter 2, Problem 29P

In tomato plants, the production of red fruit color is under the control of an allele R. Yellow tomatoes are rr. The dominant phenotype for fruit shape is under the control of an allele T, which produces two lobes. Multilobed fruit, the recessive phenotype, have the genotype tt. Two differ-ent crosses are made between parental plants of unknown genotype and phenotype. Use the progeny phenotype ratios to determine the genotypes and phenotypes of each parent.

Cross 1 progeny:

3 8 two-lobed, red

3 8 two-lobed, yellow

1 8 multilobed, red

1 8 multilobed, yellow

Cross 2 progeny:

1 4 two-lobed, red

1 4 red two-lobed, yellow

1 4 multilobed, red

1 4 multilobed, yellow

In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp  kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a tall plant with white flowers produces 3/8 tall purple, 1/8 tall white, 3/8 dwarf purple, and 1/8 dwarf white. What is the genotype of the parents? a. Dd Pp x Dd pp     b. DD Pp x dd pp     c. DD Pp x dd Pp     d. Dd Pp x Dd Pp     e. Dd pp x dd Pp
In cucumbers, orange fruit color (R) is dominant over cream fruit color (r). A cucumber plant homozygous for orange fruit is crossed with a plant homozygous for cream fruit. The F1 are intercrossed to produce the F2.a. Give the genotypes and phenotypes of the parents, the F1, and the F2.b. Give the genotypes and phenotypes of the offspring of a backcrossbetween the F1 and the orange-fruited parent.c. Give the genotypes and phenotypes of a backcross between the F1 and the cream-fruited parent
