For the cross in Part B, predict the frequencies of each of the phenotypes in the F1 progeny, and determine the genotype(s) present in each phenotypic class. Complete the diagram by dragging the correct label to the appropriate location. Labels can be used once, more than once, or not at all.

Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele (Y) is dominant to the green allele
(y).
The table below shows the F1 progeny that result from
selfing four different parent pea plants.
Use the phenotypes of the F1 progeny to deduce the
genotype and...

In this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.

. . . Activity E. Predicting the outcome of a dihybrid cross The resulting phenotypic ratios in the F2 generation of a dihybrid cross (2 traits) can be quite different than those observed from a monohybrid cross. But the process is essentially the same. First you list all possible gametes each parent and subsequent parents can produce. Second, you then assign the gamete possibilities to the Punnett square and fill it in. Finally you count the progeny and determine the...

Part B - Deducing genotypes of crossed parents A plant grown from a [round, yellow] seed is crossed with a plant grown from a [wrinkled, yellow] seed. This cross produces four progeny types in the F [round, yellow], [wrinkled, yellow], [round, green], and [wrinkled, green]. Use this information to deduce the genotypes of the parent plants. Indicate the genotypes by dragging the correct label to the appropriate location.

4. You cross individuals with the following Genotypes, AaBbDdEeFFGg & AaBbDDEeFfGg. Predict the proportion of offspring that would show the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AabbDdEeFfgg, C) the Genotype: AABbDdEeFfgg, D) the Genotype: aaBbddEeffGg, & E) all Recessive Phenotypes. 5. You cross individuals with the following Genotypes, AaBbDdEeFFgg x AabbDDEeFfGg.

Part B Determining genotypes in pedigrees of X-linked
conditions
The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal
recessive) to each pink target. Drag one blue label (for condition
B, X-linked recessive) to each...
