. What is the basis for the green-and-white color variegation in the leaves of Mirabilis? If the following cross ismade,variegated / × green what progeny types can be predicted? What about thereciprocal cross?
What phenotypes in what ratio would be expected in the F2 generation of the cross with the following information:
The genotype of homozygous black, long haired rabbit is BBhh
The genotype of homozygous brown, short haired rabbit is bbHH
The gamete of homozygous black, long haired rabbit is Bh
The gamete of homozygous brown, short haired rabbit is bH
F1 progeny is BbHh (heterozygous black, short haired rabbit)
Independent assortment predicts a 9:3:3:1 ratio in a dihybrid cross, with four different phenotypes in the F2 progeny. If there were epistasis between the two loci, what would you predict?
O more than four phenotypes
O fewer than four phenotypes
O no change in the 9:3:3:1 ratio
O an excess of parental phenotypes
O heterozygotes with an intermediate phenotype

- More Crosses with Pea Plants: The Principle of Independent Assortment Two traits are examined simultaneously in a cross of two pure-breeding pea-plant varieties. Pod shape can be either swollen or pinched. Pea color can be either green or yellow. A plant with the traits swollen and green is crossed with a plant with the traits pinched and yellow, and a resulting F1 plant is self-crossed. A total of 640 F2 progeny are phenotypically categorized as follows: 360 swollen yellow 120 swollen green 120 pinched yellow 40 pinched green a. What is the phenotypic ratio observed for pod shape? Pea color? b. What is the phenotypic ratio observed for both traits considered together? c. What is the dominance relationship for pod shape? Pea color? d. Deduce the genotypes of the P1 and F1 generations.arrow_forwardMore Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?arrow_forwardVariations in Gene Expression In a cross involving polygenic inheritance, three (3) gene pairs control plant height. The shortest and tallest plants are 12 cm and 24 cm, respectively. What height should all F1s display if the shortest and tallest plants were crossed, assuming environmental factors are the same.

- In peas, green pods(G) are dominant to yellpw pods(g) and inflated pods(I) are dominant to constricted pods(i). Cross an individual heterozygous for both trairs with an individual that has yellow, constricted pods. Using the five steps, show the possible phenotypes and their ratios(as fractions) for this cross.

The heterozygous condition results in orange (Rr) flower color. A short plant with red flowers, is crossed with a plant homozygous for tallness and yellow flowers.

- Assume the height in a particular plant is determined by two pairs of unlinked polygenes, each effective allele contributes 5cm to a base height of 10cm. What are the heights of each parent? What height is to be expected in the F1 if there are no environmental effects? What is the expected phenotypic ratio in the F2arrow_forwardMendelian ratios are modified in crosses involving autotetraploids.Assume that one plant expresses the dominant trait greenseeds and is homozygous (WWWW). This plant is crossed to onewith white seeds that is also homozygous (wwww). If only onedominant allele is sufficient to produce green seeds, predict theF1 and F2 results of such a cross. Assume that synapsis betweenchromosome pairs is random during meiosis.arrow_forwardincomplete dominance What is the phenotype of the plant with RR genotype?
