The weight of the fruit of one variety of squash is determined by three pairs of...
The weight of the fruit of one variety of squash is determined by three pairs of genes: AAB-BCC, producing 6-pound squashes and aabbcc, producing 3 pound squashes. Each dominant gene adds 1/2 pound to the weight. When a 6 pound squash is crossed with a 3 pound squash, all of the offspring weighed 4.5 pounds. What would be the weights of the F2 fruits if two of these F1 plants were crossed?

The weight of fruit in a plant is determined additively by 3 genes. A plant having all recessive alleles has a fruit weight of 2 g. A plant having all dominant alleles has a fruit weight of 8 g. Determine the range of weights (minimum and maximum) for the offspring of the following cross: AA Bb CC x aa Bb Cc 4 – 7 grams 2 – 8 grams 4 – 8 grams 2 – 5 grams

Analyze the following fruit fly cross. In this cross there are two autosomal traits that are influenced by two distinct genes and the F2 generation came from crossing an F1 male with an F1 female. P: true breeding grey eyed; brown bodied males x true breeding red eyed; black bodied females F1: all offspring are red eyed; brown bodied F2: ? When the Fy flies are allowed to self cross, what percentage of F2...

6. In Cross 1, a yellow eyed, long wing fruit fly from a pure breeding strain is mated to a red eye, short wing fruit fly from a pure breeding strain. All of their offspring (F1) had red eyes and long wings. In Cross 2, one of the F1 offspring is mated to a fly with yellow eyes and short wings, and this cross gave the following F2 population: 194 flies with long wings and red eyes, 796 flies with...

Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...
