In corn plants, a dominant allele Z inhibits kernel color, while the recessive allele z permits color when homozygous. At a different locus, the dominant allele X causes purple kernel color, while the homozygous recessive genotype causes red kernel color. If corn plants heterozygous for both the Z and X genes are crossed, what are the chances that the offspring will have purple kernels? Enter your answer as a decimal fraction in the box (e.g. 0.25).
In a certain type of pea plant, the gene for yellow color (Y) is dominant to the gene for green color (y), and the gene for round shape (R) is dominant to the gene for wrinkled shape (r). If a homozygous dominant plant is mated with a homozygous recessive plant (P-gen), what proportion in the F2 generation will be homozygous recessive? a) 1/4 b) 1/16 c) 3/4 d) 3/8
In flowers, purple flower color is dominant and denoted by "P" while white flower color is recessive and is denoted by "p". In a monohybrid cross between 2 heterozygous purple flowers, what is the expected phenotypic offspring ratio?
In a genetic cross between a homozygous tall plant with homozygous purple flowers and a homozygous short plant with heterozygous purple flowers, how many short plants will you expect in the F2 generation if you sample 36 individuals? Both tall and purple are dominant.
A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Identify the: Parents’ genes?Parents’ traits?Genes (genotype)?Shape, color? (phenotype)?Genotypic ratio?Phenotypic ratio?
. In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals?
In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals? Set up a Punnett square for the dihybrid cross.
In peas, purple flowers are dominant to white. If a purple-flowered, heterozygous plant were crossed with a white-flowered plant, what is the expected ratio of genotypes and phenotypes among the F1F1offspring? If two of the purple-flowered F1F1 offspring were randomly selected and crossed, what is the expected ratio of genotypes and phenotypes among the F2F2 offspring?
Suppose a species of tulip has three alleles for the gene that codes for flower color. The CR allele produces red tulips, the CB allele produces blue tulips, and the CW allele produces white tulips. Both CR and CB are dominant over CW, but CR and CB are incompletely dominant with each other, so CRCB heterozygotes have purple flowers. What is the expected phenotypic ratio in the offspring of the following crosses, in the order red : blue : purple : white? Enter your answers as the most simplified ratio (e.g. 1 : 2 : 1 : 1 instead of 2 : 4 : 2 : 2). Enter 0 if none of the offspring from a cross will be a particular color.
