. . . 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...

with brown fur and all offspring had black fur. ne of the resulting F2 progeny were brown 7. A guinea pig with black fur was bred to one with brown fur and all offspring na When two of these F1 offspring were bred, some of the resulting F2 progeny while others were black. a. What is the dominant phenotype? How do you know?__ b. Create symbols to represent the alleles for coat color in guinea pigs. Black = Brown =...

Question 12 only.
Punnett's square analysis for the parental cross r Rr Rr 9) If we used the above offspring (F1) in a new cross, what would be the genotypes and phenotypes of the offspring of the Fz generation? 10) What is the genotypic ratio of the F2 generation? 11) What is the phenotypic ratio of the F2 generation? 12) What would be the genotypic and phenotypic ratios of offspring from a cross between a homozygous recessive parent (r r)...

Use the interactive Punnet Squares Level 2 to answer the following questions. Suppose the parents indicated in the interactive produced 208 peas. Determine the expected number of yellow and wrinkled offspring Number Now suppose one of the pea plants is homozygous recessive for both genes, resulting in the cros Yy Rrxyy IT. Calculate the percentage of yellow and wrinkled offspring Number Suppose one of the pea plants is homozygous recessive for seed color, resulting in the cross Yy Rr xyy...

10) What is/are the parental phenotypic type(s) you predict in
the F2 (progeny of the F1 cross)?
11) What is/are the recombinant type(s) you predict in the F2

12) Now that you can distinguish parental vs recombinant types,
you can calculate the recombination between w+ and m+:

The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
2)...
