- True breeding eggplant plants producing deep, purple colored fruit are crossed with true breeding plants producing white fruit. The offspring of this cross all produce lighter, violet fruit. The colors of the fruit are produced by the interactions of the two different alleles. A.Predict the genotype of the F1 plant. B. Predict the expected proportions and genotypes in the F2 generation, if F1 eggplants are crossed.A is dominant over a and B is dominant over b. Genes A/a and B/b assort independently. The parental cross (P) is between true- breeding (homozygous) strains (AA bb x aa BB). The resulting F1 offspring would be [Select ] A F1 x F1 cross gives the F2 generation. The ratio of phenotypes in the F2 generation can be described as [ Select ] In the phenotypic ratio, what number refers to individuals that are: dominant for both traits? [ Select ] recessive for both traits? [Select ] To what phenotypes do the "3"s in the ratio refer? [ Select ] > >shows the results of a dihybrid cross involving seed shape and seed color. a. What proportion of the round and yellow F2 progeny from this cross is homozygous at both loci? b. What proportion of the round and yellow F2 progeny from this cross is homozygous at least at one locus?

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 greenLeaf color and stem length in a certain species of diploid flowers are controlled separately by the R and S locus. The R allele (dominant) results in red leaves while r results in yellow leaves. S (dominant) results in short stems and s results in long stems. A cross is performed between a true breeding long-stemmed red plant and a true breeding short- stemmed yellow plant. a. What is the genotype and phenotype of the resulting F1 plants? b.
