In peas, the dominant R allele produces peas that are round, whereas the recessive r allele produces peas that are wrinkled. The dominant Y allele produces yellow peas, and the recessive y allele produces green peas. If two heterozygous round, yellow pea plants (RrYy) were crossed (RrYy X RrYy), answer the following regarding the possible progeny. Question: What proportion of the offspring will have the genotype Yy? Question 11 options: 1/4 1/2 3/4 1/16
If body-color B is dominant to green body color b what would the genotype be for a heterozygous individual be? Using the blue B and a green b body color from above create a Punit square that represents the offspring of two heterozygous parents? what is the probability that they will have a child with a green body-color If the child is green what is its genotype? Cross a green parent with a homozygous blue parent. What color will their kids be?
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).
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? Construct the punnet square, then identify the following: 1. Parents’ genes?2. Parents’ traits?3. Genes (genotype)?4. Shape, color? (phenotype)?5. Genotypic ratio?6. Phenotypic ratio?
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?
To identify the genotype of yellow seeded pea plants as either homozygous dominant (YY) or heterozygous (Yy), you could do a test cross. If 50% of the offspring are yellow-seeded and 50% are green what is the genotype of the parents? A)Yy and YyB)Yy and yyC)YY and YyD)yy and yyE) YY and yy
In a heterzygote cross between two peas, where A is dominant and a is recessive. In a pod with 4 peas, what is the probability that 3 or more of the peas are recessive.
In snapdragons, heterozygotes for one of the genes have pink flowers, whereas homozygotes have red (R) or white (r) flowers. When plants with red flowers are crossed with plants with white flowers, what proportion/probability of the offspring will have pink flowers? Create a Punnett square.
You have a pea plant with a yellow pea phenotype but do not know if the genotype is homozygous (YY) or heterozygous (Yy). What type of cross would you do determine the genotype of this plant and what would be the predicted phenotypes of the offspring?
The following cross is set: DDEeFFggHh X DdEEFfGGhh a. What is the maximum number of additive alleles possible in their offspring? b. What is the maximum number of non-additive alleles possible in their offspring?
A heterozygous pea plant of both traits is crossed with a recessive pea plant of both traits. What is the probability that the offspring will be tall and yellow?
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? A - 1/2B - 1/4C - 1/8D - 1/16
