**Transcription and Explanation for Educational Website**---**Question:**In the snail *Capaea nemoralis*, an autosomal allele causing a banded shell (B^B) is recessive to the allele for an unbanded shell (B^0). Genes at a different locus determine the background color of the shell; here yellow (C^Y) is recessive to brown (C^BW). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F₁ are then crossed with banded, yellow snails (a test cross).**Diagrams:**There are two empty rectangular spaces likely intended for users to fill in or for further explanation related to genetic diagrams such as Punnett squares.**Question c:**What will the results be of the test cross if the loci ARE linked and 20 m.u. apart?---**Explanation for Diagrams:**While the diagrams themselves are empty, a potential explanation could involve illustrating the expected outcomes of genetic crosses. In the context of this problem, diagrams could include:1. **Punnett Square for Initial Cross:** - A square showing the genetic combinations from crossing a banded, yellow snail (B^B C^Y) with a homozygous brown, unbanded snail (B^0 C^BW).2. **Punnett Square for Test Cross:** - A square illustrating genetic outcomes when F₁ individuals (heterozygous) are crossed with banded, yellow snails, considering the loci are linked and 20 map units apart.Each diagram can demonstrate the theoretical genetic makeup of offspring based on the provided genetic characteristics and linkage information.

in the snall Capded nemoralis, an autosonmal allele causing a banded (Bº) is recessive to the allele for an unbanded shell (B°). Genes at a different locus determine the background color of the shell; here yellow (C') is recessive to brown (C®w). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a test cross).

In Drosophila melanogaster, ebony body color is determined by the e allele. The e+ allele produces the wild-typehoney-colored body. In heterozygotes, the body is honey-colored except for a dark marking called the trident seen on the thorax. The e+ allele is thus considered to be incompletely dominant to the e allele.a. When female e+ e+ flies are crossed to male e+ e flies, what is the probability that progeny will have the tridentmarking? Animals with the marking mate among themselves. Of 100 progeny, how many would be expected to have a trident, how many would have ebony bodies, and how many would have honey-colored bodies?
Two autosomal genes controlling beak shape in finches are 18 cM apart on the same chromosome. Pointy beaks (P) are dominant to round beaks (p), and narrow beaks (N) are dominant to wide beaks (n).

Your internship with Dr. Nefario at Gru Industries is going well so far, but a recent mission to obtain a shrink ray requires a special kind of Minion. You identify that the ideal Minion phenotypes for this mission are two eyes, pale yellow, and short. From your previous work, you’ve found that:Two-eyed (D) is completely dominant over one-eyed (d)Yellow (Y) is incompletely dominant with white (y)Tall (T) is completely dominant over short (t) a. The only reproductive individuals you have at the moment (it was surprise mission!) are a true breeding two-eyed, yellow, short Minion and a one heterozygous for each trait. What genotypic ratios would you expect for this crossassuming that each locus is on a different chromosome? What total proportion would you expect to be the desired phenotype for the mission? b. The mission has since been delayed due to lack of financial support, so you’ve got some time. All the individuals from the F1 cross above are now reproductive. Which genotypes would…
Miniature wings in Drosophila result from an X-linked allele (w) that is recessive to the allele for long wings (+). In a cross of a long winged male with a long winged female, the following offspring were obtained: 100 long winged males, 106 miniature winged males, and 480 long winged females. Given this result, the female must be a carrier of the miniature wing allele. True False

In a certain plant, the dominant form of gene B codes for blue fruit, while the recessive form results in pink fruit. The dominant form of another gene, E, inhibits the activity of the enzyme coded for by gene B, resulting in white fruit, while the recessive form is unable to inhibit this enzyme and results in colored (i.e., blue or pink) fruit. A doubly-homozygous dominant white-fruited plant is crossed with a pink-fruited plant. The F1 progeny were then self-crossed to generate the F2 generation. Determine the ratios of genotypes and phenotypes for each generation.
In the garden pea, orange pods (o) are recessive to green pods (+), and sensitivity to pea mosaic virus (v) is recessive to resistance to the virus (+). A plant with orange pods and sensitivity to the virus was crossed to a true-breeding plant with green pods and resistance to the virus. The F1 progeny were then test-crossed to plants with orange pods and sensitivity to the virus with the following results: 160 orange pods, virus sensitive 36 orange pods, virus resistant 165 green pods, virus resistant 39 green pods, virus sensitive A goodness of fit analysis for the operative genetic mechanism behind these obtained results will result to a X2 value of ____ which is (below, above) the alpha value, and interpreted as (significant, not significant).

In the fruit fly, dumpy wings (d) and purple eyes (p) are encoded by mutant alleles that are recessive to those that produce wild type traits; long wings (d+) and red eyes (p+). These two genes are on the same chromosome. In a particular lab, two researchers Walt and Jesse crossed a fly homozygous for dumpy wings and purple eyes with a fly homozygous for the wild type traits. The F1 progeny, which had long wings and red eyes, was then crossed with flies that had dumpy wings and purple eyes. Unfortunately, the progeny of this cross somehow escaped. To prevent their other projects from contamination, they decided to spend an exceptionally boring hour in the lab catching and counting the progeny and found the following: long wings, red eyes – 482 dumpy wings, purple eyes – 473 long wings, purple eyes – 23 dumpy wings, red eyes - 22 What is the genetic distance between these two loci? a. 4.5 cM b. 55 cM c. 45 cM d. 49.5 cM e. 4.7 cM
