Assume independent assortment and start with a plantthat is dihybrid A/a ; B/b:a. What phenotypic ratio is produced from selfing it?b. What genotypic ratio is produced from selfing it?c. What phenotypic ratio is produced from testcrossingit?d. What genotypic ratio is produced from testcrossingit

In peas, tall (T) is dominant to short (t). A homozygous tall plant is cross with a short plant. The F1 are self fertilized to produce the F2. Both tall and short plants appear in the F2. If the tall F2 are self fertilized, what types of offspring and proportions will be produced? (Show all your work) please use the punnet square

In pea plants, spherical seeds (S) are dominant to dented seeds (s). In a genetic cross of twoplants that are heterozygous for the seed shape trait,i. Explain the diagram ii. What fraction of the offspring should have spherical seeds? iii. Use punnett square to show your answer. iv. Interpret the results of a Punnett square

ibri 12 BIU A - A 4. 11. Mendel crossed peas having round seeds and yellow cotyledons with peas having wrinkled seeds and green cotyledons. All the F1 plants had round seeds with yellow cotyledons. a. What are the genotypes of the parent plants? b. What gametes could be produced by the parent with round seeds and yellow cotyledons? C. What gametes could be produced by the parent with wrinkled seeds and green cotyledons? d. What is the genotype of the F1 plants? e. What gametes could be produced by the F1 plants? hp

A researcher crosses two white-flowered lines ofAntirrhinum plants as follows and obtains the followingresults:pure line 1 × pure line 2↓F1 all whiteF1 × F1↓F2 131 white29 reda. Deduce the inheritance of these phenotypes; useclearly defined gene symbols. Give the genotypes ofthe parents, F1, and F2.b. Predict the outcome of crosses of the F1 with eachparental line.

a. What type of trait is this? How many genes and alleles are involved? Explain your answer. b. What are the genotypes of the 90 and 100 cm plants respectively in the parental generation? c. What is the possible genotype, or genotypes, of the 95 cm class in the F2? c. What is the possible genotype, or genotypes, of the 95 cm class in the F2?

An individual pea plant is heterozygous for two loci: height and seed shape, with the genotype TtRr. These two loci are on different chromosomes and assort independently. What gametes are produced by this plant? Select all that apply. rr RR tr Tr tR tt TR TT TtRr

Mendel performed crosses in which he used pollen from a white-flowered plant to fertilize a purple-flowered plant and pollen from a purple-flowered plant to fertilize a white-flowered plant, showing the same results with both. What did these reciprocal crosses demonstrate?     A.  That the plants were not sterile.  B.  That there was no epistasis.  C.  That the trait could be passed from either parent.  D.  B and C.

A researcher crosses two tall plants, however, one quarter (1/4) of the offspring from this crossing have short stems. Complete the punnett square. 6 b EBE Bb Besides Bb, what is the other possible genotype for a tall plant? What is the genotype of a short plant? Bb bb
