A pure-breeding strain of squash that produced disk-shaped fruits was crossed with a pure breeding strain having long fruits. The F1 had disk fruits, but the F2 showed a new phenotype, sphere, and was composed of the following proportions
Disk 384
Sphere 96
Long 32

If a homozygous plant with red peppers is crossed with a homozygous plant with green peppers, all the F1 plants have red peppers. When the F1 are crossed with one another, the F2 are in a ratio of 9 red : 3 brown : 3 yellow : 1 green due to

In corn, three dominant alleles, called A, C, and R, must be present to produce colored seeds. Genotype A/–; C/– ; R/– is colored; all others are colorless. A colored plant AaCCRr is crossed with colorless plant aaCcRr. What proportional of offspring plant with colorless seed?

Two independent pure line varieties having white and green phenotype in their fruit were cross, the all f1 progeny is white fruit. The F2 progeny obtain from selfing show white, yellow and green in ratio of 12:3:1. Which of the following is correct?

Red kernel color in wheat results from the presence of at least one dominant allele of each of two independently segregating genes . Kernels on rr bb plants are white, and the genotypes R— bb and rr B— result in brown kernel color. Suppose that plants of a variety that is true breeding for red kernels are crossed with plants true breeding for white kernels produced F1 were allowed to selfing .what are F2 phenotype ratio ?
