Can you please find the best conclusion answer for this problem? Suppose you have a species of butterflies with three different colors:Red, Yellow, and Green. You cross a true-breeding Red line and a true-breeding Yellow line. The F, progeny are all Red, with no traces ofYellow or Green pigment present. Then, you take the F, progeny andcross them to each other. In the F2 generation you see a 3:1phenotype ratio of Red : Yellow progeny. What is the most likelyconclusion you can draw from these results?Red and Yellow are two alleles at the same locus, where Yellowis dominant and Red is recessive.O Red, Yellow, and Green pigments are determined by co-dominantalleles at the same locus.O Red and Yellow are two alleles at the same locus, where Red isdominant and Yellow is recessive.O Red and Yellow are encoded by two alleles at the same locus,which show incomplete dominance.O Red, Yellow, and Green pigments are sex-linked alleles, soGreen only shows up in certain crosses.

The solution of this question can be applied by using basic principles of genetics given by the…

Vith three COlors: Red, Yellow, and Green. You cross a true-breeding Red line and a true- breeding Yellow line. The F, progeny are all Red, with no traces of Yellow or Green pigment present. Then, you take the F, progeny and cross them to each other. In the F2 generation you see a 3:1 phenotype ratio of Red : Yellow progeny. What is the most likely conclusion you can draw from these results?

Imagine that you are performing a cross involving seed color in garden pea plants. What traits would you expect to observe in the F1 offspring if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. a. only yellow-green seeds b. only yellow seeds c. 1:1 yellow seeds:green seeds d. 1:3 green seeds:yellow seeds
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?

We have crossed true-breeding flies today. Wild type to mutant. Their phenotypes were wt and vg se. (Let’s not worry about males and females for now, just assume both genes are autosomal, which is normal in a Mendelian experiment). The results of a cross are phenotypes. I will be asking you for numbers or a ratio of phenotype numbers you expect to see in the offspring from this cross. To answer this, you’ll need to start with the genotypes of parents, then write their gametes, then write the offspring genotypes, then get the phenotypes based on them. Predict the results of this cross: In case both mutations are recessive; In case both mutations are dominant; In case vestigial wings are recessive and the sepia eyes are dominant.
You perform a cross between two true-breeding strains of zucchini, One has green fruit and the other has yellow fruit. The F1 plants are all green, but when these are crossed, the F2 plants consist of 9 green: 7 yellow. A. Assuming that wild-type zucchini are green, how would you describe the phenomenon that occurred in the F1 of part (e) of the parents and progeny?.
You cross a black dog which is homozygous dominant for two genes B and E (B determines pigment production and E determines deposition of pigment) with a yellow dog homozygous recessive for both genes and then intercross the F1, you obtain a progeny in the ratio of 9 (black) : 3 (brown) :4 (yellow). Explain the results (specially why you don't get the usual 9:3:3:1 ratio)
You are studying 2 traits, fur color and length, in rabbits. You cross a true-breeding brown, short furred rabbit with a true-breeding white, long furred rabbit. The F1 offspring are all white, short furred rabbits. You then cross an F1 offspring to a rabbit homozygous recessive for both traits. Assuming that fur color and fur length are independently assorting, what phenotypic ratio would you expect to see in the F2 generation? white, short: white, long: brown, short: brown, long
A particular breed of dog can have long hair or short hair. Whentrue-breeding long-haired animals were crossed to true-breedingshort-haired animals, the offspring all had long hair. The F2 generation showed a 3:1 ratio of long- to short-haired offspring. Asecond gene affects the texture of the hair. The two variants arewiry hair and straight hair. F1 offspring from a cross of these twovarieties all had wiry hair, and F2 offspring showed a 3:1 ratio ofwiry-haired to straight-haired puppies. Recently, a breeder of theshort- and wiry-haired dogs found a female puppy that was albino.Similarly, another breeder of the long- and straight-haired dogsfound a male puppy that was albino. Because the albino trait is always due to a recessive allele, the two breeders got together andmated the two dogs. Surprisingly, all of the puppies in the litterhad black hair. How can you explain this result?
In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. 9) You take an F1 male and an F1 female to generate F2 offspring. You take an F2 male with round and yellow seeds and mate them with an F2 female that has round green seeds. If these F2s produce 108 offspring, how many would be predicted to be green and wrinkled? a) 27 b) 3 c) 4 d) 7 e) 12
You are attempting to map the chromosome of a silk moth. You know that red eyes and white banded wings are recessive to the wild type eyes and wings. You cross a homozygous recessive moth with a homozygous dominant moth. The f1 generation has all wild type traits. You then allow the f1 progeny to interbreed and acquire the following numbers: Wild type eyes and wild type wings -418 Red eyes and wild type wings -16 Wild eyes and white banded wings- 16 Red eyes and white banded wings - 426 Determine the recombination frequency of Red eyes and white banded genes. Also, determine the distance between them.
You cross pure breeding plants with short stamens and white flowers to plants (also purebreeding) with long stamens and blue flowers. All the F1 have white flowers and long stamens. You cross the F1 to another strain of plants, pure breeding for blue flowers and short stamens. The F2 progeny are: 12 White and Long, 85 White and short, 8 Blue and short, 95 blue and long. What is the distance between the two genes? 10 mu 90 mu 1 mu 20 mu They are not linked
A pure-bred male fruit fly with red eyes and short wings is mated with a pure-bred female fly with white eyes and long wings. If Red eyes and Long wings are dominant, indicate what the genotype and phenotype of the F1 would be. Then show the punnett square for the second generation (you do NOT need to fill it out) and list the phenotypic ratio.
