Hypothesis: When a wild-type Red eye colored parent is crossed with White eye colored parent, most of the offsprings obtained in F1 generation will be with Red eye color.
| Red / White | R | R |
| r | Rr | Rr |
| r | Rr | Rr |
When the parents of Red homozygous was crossed with white homozygous, all the offsprings are with Rr genotype carrying one R allele for Red color and r allele for white color.
The major change observed is the change in genotype. The Red eyed offsprings are with the genotype Rr unlike the Red eyed parent RR

Using the Fly Breeder tool in the Fly Biolab, we analyze the heritability of eight other traits. Based on the phenotype ratios observed, explain whether each trait is caused by a dominant or recessive allele, and whether the trait is autosomal or sex-linked. Support each conclusion by referring to a completed Punnett Square. Trait 1: Purple Eyes Parent Phenotypes: Male- Red Eye Female- Purple Eye F1 Results (phenotype ratios): 100% red eyes F2 Results (phenotype ratios): 75% red: 25% purple...

Genetics questions, i need help!
1) For the Drosophila red/white cross, you crossed red females and white males (w'w, wy). a) Draw the Punnett Square for this cross (F1). What is the ratio of red females:red males? b) Suppose in the F1 generation, you observed 70 red females and 30 red males. Do a Chi- Square Test to test the hypothesis of the ratio you found in part (a) above. Do you accept or reject the hypothesis? c) Draw the...

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
(progeny of the F1 cross)?
12) Now that you can distinguish parental vs recombinant types,
you can calculate the recombination between w+ and m+:
write the fraction and calculate the recombination
frequency:
number of recombinant
types
_______________________ = ___________ =
Total number of
progeny
Now express the recombination frequency in centimorgans:

1. What kind of assortment does the F2 generation exhibit? Which of Mendel’s laws does it support? 2. What are the genotypes of both of the first parent plants? 3. Why do the F1 generation plants only contain tall plants with red flowers? Why are there no short plants or white flowers? 4. According to the activity, what is the genotype for the F1 Generation? What is their phenotype? 5. From the Punnett Square, what is the ratio of short-white...

2. You cross a homozygous wildtype female Drosophila (fruit fly) with a male that has a black body (bb). You mate two of the F1 (first generation) flies and examine the F2 (second generation) offspring. The phenotypes can be seen in the table below. a. Draw a pedigree to show the P, F1, and F2 generations. You only need to draw one fly with each phenotype for the F2 generation. seen in this cross. the expected values for a cross...

When red flowered snap dragons are mated with white flowered snap dragons, all of the F1 progeny are pink. Assuming this trait is controlled by a single gene with two partially dominant alleles, what progeny would you expect if a pink flowered snap dragon were mated with a red flowered snap dragon? Draw a Punnett square to support your answer.
