Dihybrid crosses involving plants with either white or yellow flower and either tall or short morphs were done. The yellow allele is dominant over the while allele, and the tall allele is dominant over the short allele. The following are the observed numbers of each combination. Do these data fit the expected distribution?

You perform a dihybrid cross of plants. The first trait is flower color. “A” is the dominant allele and causes red petals and “a” is the recessive allele and causes white petals. Stem length is the second trait. “L” is the dominant allele and causes a long stem and “l” is the recessive allele and causes short stems. You cross a Red Long plant that is heterozygous for both traits with a Red Short plant that is heterozygous for color....

A white, disc-shaped squash crosses with a yellow, sphere-shaped squash and gives 29 white, disc-shaped; 26 white, sphere-shaped; 25 yellow, disc-shaped; and 24 yellow, sphere-shaped. If the white, disc-shaped parent is self-fertilized, what fraction of its offspring will be yellow, sphere-shaped?

In garden peas, tall plants are dominant to short plants and smooth seeds are dominant over wrinkled seeds. If two heterozygous tall plants with smooth seeds (TtRr) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? What are the gametes for each parent? What is the phenotypic ratio? What proportion of the Tall plants with smooth seeds is heterozygous for both traits?

According to a theory in genetics, if tall and colorful plants are crossed with short and colorless plants, four types of plants will result: tall and colorful, tall and colorless, short and colorful, and short and colorless, with corresponding probabilities: 0.37, 0.42, 0.11 and 0.10. ten plants are selected. find the probability that 5 will be tall and colorful, 2 will be tall and colorless, 2 will be short and colorful, and 1 will be short and colorless.

In violets, purple is dominant to white and tall stems are dominant to short stems. . A tall purple plant that is heterozygous at both loci is crossed with a double homozygous recessive plant. What is the probability of obtaining either a tall white plant or a short purple plant? What percent of the offspring are expected to be heterozygous at one or both loci? What will be the expected ratio of the F2 offspring of the F1 generation?
