4. In summer squash, fruit color and shape are controlled by two independently assorting genes as follows: Trait Gene Alleles Phenotypes Fruit color W W w White fruit yellow fruit Fruit shape D D d Disk-shaped fruit sphere-shaped fruit A homozygous White Disk plant has been crossed with a homozygous Yellow Sphere plant (this is the P1 generation).

For problems 38 and 39 assume that in squashes the difference in fruit weight between a 3-1b type and a 6-lb type results from three independently segregating allele pairs with each capital letter contributing a half pound to the weight of the squash. 38. What is the range in fruit weight of the offspring in the following cross: Aa Bb Cc x Aa Bb Cc 39. A farmer develops a 4-lb variety of the squash that is true breeding. What...

A homozygous variety of opium poppy (Papaver somniferum Laciniatum) with lacerate leaves was crossed with another homozygous variety with normal leaves. All the Fj had lacerate leaves (jagged-edged leaves). Two F1 plants were crossed to produce the F2. Of the F2, 249 had lacerate leaves and 16 had normal leaves. How are lacerate leaves determined in the opium poppy? two genes, with a dominant allele at either or both loci one gene, with codominant alleles at a single locus two...

Please provide details: White fruit color in summer squash is governed by a dominant gene (W) and colored fruit by its recessive allele (w). Yellow fruit is governed by an independently assorting hypostatic gene (Y) and green by its recessive allele (y). When dihybrid plants are crossed, the offspring appear in the ratio of 12 white : 3 yellow : 1 green. What fruit color ratio is expected from the cross of WwYy to Wwyy? 1/2 white, 1/4 yellow, 1/4...

When two 12 pound F2 trees were crossed they produced offspring which all produced 12 pound fruit. However, when these offspring were crossed randomly, the fruit produced weighted from 4 to 20 pounds. What can you say about the possible genotypes of the original F2 trees? 65 AJ. Jones...

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
The weight of the nut of a commercially valuable species was determined to be under the...
The weight of the nut of a commercially valuable species was determined to be under the control of two genes. Each locus can be occupied by either an additive or non-additive allele, and the effect of the additive alleles is approximately equal. In a population study, two true-breeding strains were isolated where the weights were 10.0 g and 13.2 g, respectively. Assuming that these strains represent the upper and lower levels of nut weight, predict * a) the weight of...

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

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...
