Concept explainers
Blue moon beans produce beans that are either the domi-nant color blue or the recessive color white. The bean pods for this species always contain four seeds each. If two heterozygous plants that each have the Bb genotype are crossed, what are the predicted frequencies of each of the five outcome classes for combinations of blue and white seeds in pods?

- In certain plants, tall (T) is dominant to short (t). If a heterozygous plant is crossed with a homozygous short plant, what is the probability that the offspring will be short? Show the punnett square please.arrow_forwardIn a dihybrid cross, a true breeding short white flowered plant is crossed with a non-true breeding tall purple flowered plant. Both tall and purple are dominant traits. What are the genotypes and phenotypes of the offspring generation and what are the ratios of each?arrow_forwardIn 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?arrow_forward
- 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.arrow_forwardIn 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?arrow_forwardA. In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and diskshaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant heterozygous fruit, what will the phenotypic and genotypic ratios be?arrow_forward
- In mice, black color (B) is dominant to white (b). On different homologous chromosomes, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance known as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both locations are crossed, what is the expected phenotypic ratio of their offspring? Use the rules of probability instead of a huge Punnett square.arrow_forwardThe genes for tall vine D and yellow seed G, are dominant over their respective alleles for dwarf d and green g. What phenotypes are expected from each of the following crosses? Include phenotypic and genotypic ratio. Use Punnet square to show the ff. Crosses. a. Heterozygous tall, homozygous yellow X Homozygous Tall, heterozygous yellow. b. Homozygous Dwarf, heterozygous yellow X Heterozygous tall, homozygous greenarrow_forwardA spotted rabbit, when mated with a solid-colored rabbit, produced all spotted offspring. When these F1 rabbits were crossed among themselves, they produced 24 spotted rabbits and 8 solid-colored rabbits. About how many of the solid-colored F2 rabbits would be homozygous? What is the genotype of the parental generation? What is the genotypic ratio of the F1?arrow_forward
- 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).arrow_forwardSummer squash color is determined by the interaction of more than one gene. The presence of CC or Cc allele combinations produces a squash that is white in color, and the C allele is epistatic to the G allele. The presence of GG or Gg produces a squash that is yellow in color, and ccgg produces a squash that is green. After two fully heterozygous squash are crossed. Give the phenotypes, and frequency of occurrence, of the F2 offspringarrow_forwardGiven a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: How many phenotypes can be expected from the cross?arrow_forward
