4. Now, assume that a F1 male and a F1 female offspring produced by the cross in #3 above mate with each other. F1 offspring : XXGgBb and XYGgBb Note: You can ignore the X and Y chromosomes here in question 4. Why? The traits of interest (fire-breathing and laser-shooting) are autosomal, so the sex of the fly (XX=female or XY=male) will not impact the trait expressed. You only need to follow the inheritance of chromosomes 2 and 3 for...

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...

If you have an F1 generation that is heterozygous for the tall/dwarf allele, cross them to produce an F2 generation. Draw a Punnett Square for that cross here. a. In the F2 generation, what is the probability that the first 3 pea plants you grow will all be tall? You must show your work. b. In the same F2 population, find the probability that 5 out of 7 plants will be tall. Use the bionomial expansion equation. This procedure is...

A dark purple eggplant (male) was crossed with a white eggplant (female). The resulting F1 were all violet (light purple), while the F2 included mostly violet, and some dark purple and white eggplants. Answer the following below. (5 pts.)

1. In Drosophilia, females are XX, while males are XY. Yellow bodies are determined by an X-linked recessive mutation Xb, while the dominant wild-type allele XB produces brown bodies. A heterozygous female is crossed with a brown bodied male to produce the F1 generation. a) Among the F1 generation, what genotypes and phenotypes would be expected among the progeny, and in what proportion? b) from the F1 generation, males and females are mated at random. What genotypes and phenotypes would...

You make cross between a male fruit fly with wrinkled wings and a female fly with vestigial wings. All of the F1 flies are have wrinkled wings. A cross between an F1 female fly and an F1 male fly yields the following offspring: 45 wrinkled-wing males 51 wrinkled-wing females 18 vestigial-wing males 14 vestigial-wing females What do you hypothesize as the mode of inheritance for this trait?

In a cross between a black and a white guinea pig, all members of the F1 generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white guinea pigs. A. Based on this cross, which trait is dominant and which is recessive? What information lead you to your conclusion? B. Diagram this cross, showing the genotypes and phenotypes of parental, F1 and F2 generations. C. What will the offspring be like if two F2 generation...
