As a student of genetics, you become interested in the phenotype of feathered legs in Black Langshan fowl and featherless legs found in Buff Rocks fowl. Your first inclination is that this trait is controlled by a single gene - two allele genetic system. To test this hypothesis you mate a true breeding Black Langshan with a true breeding Buff Rocks, and all of the offspring develop feathered legs. Reciprocal crosses yielded the same results. Using an allele system of your choice, describe this cross.

Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
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
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
In the video game Animal Crossing: New Horizons, flowering breeding is based in genetics. Each flower's color is determined by the genotype at three or four unlinked genes: R, Y, W, and S. The genotype of the elusive blue rose is RR YY ww ss. In the game, one way to get a blue rose is to cross two roses with the Rr Yy Ww ss genotype. A) What types of gametes and in what proportions will a Rr Yy Ww ss rose produce? B) In a cross Rr Yy Ww ss x Rr Yy Ww ss what are the possible offspring genotypes and at what frequency will they each appear? Show your work. C) What proportion of the offspring of the cross will be blue roses?
When crossing a true breeding white mouse with a true breeding brown mouse your friend tells you she recovered all black mice. But then when she crosses the F1 mice to each other she recovered 28 black mice, 8 brown mice, and 13 white mice. Can you help her explain these results? (Type out the cross and include genotypes of as many mice as possible. What phrase best describes this phenomenon? How many genes are involved are they linked or unlinked? Etc.)
Fruit flies having one allele for curly wings (Cy) and one allele for normal wings (Cy+) develp curly wings. Fruit flies homozygous for normal wings (Cy+) develop normal wings. When two curly-winged flies were crossed, 204 curly-winged and 98 normal-winged flies. In fact, all crosses between curly-winged flies produce nearly the same curly-winged to normal-winged ratio. How would you explain these results? The Cy allele is epistatic to the Cy+ allele. The Cy+ allelle shows partial dominance over the Cy allele. The Cy allele is dominant for the curly phenotype and is lethal when homozygous. The Cy+ allele is dominant over the Cy allele and is lethal when homozygous. The Cy+ and Cy alles are co-dominant.
Pigeons display a high color variety, here we try to understand the genetic basis of mixed red & black stippling of the feathers (kitey) and their genetic relation to black and red feather color. We conducted the following crosses: Cross Offspring kitey x kitey 16 kitey 5 black 3 red kitey x black 6 kitey 7 black red x kitey 18 red 9 kitey 6 black Have a look at the cross results and develop a hypothesis to explain the inheritance of kitey, black and red feather color in pigeons (Hint: assume that 2 loci are involved and some type of epistasis occurs) QUESTION: 1. provide hypothesis 2. provide the hypothetical genotypes for each crossing
Consider a dominant pure-breeding parent pea plant that had green peas, was tall, and had purple flowers, was crossed with a recessive pure-breeding parent that had yellow peas, was short, and had white flowers. In order to produce a gene map, Doja Cat selects a single F1 heterozygote offspring and test crosses it to produce 80 F2 offspring that collectively exhibit eight different phenotypes with 10 organisms of each phenotype. Can she automatically assume that the three genes in the pea plants were linked?
In a breeding experiment, two heterozygous purple heterozygous tall plants are crossed. Solve for the phenotypic and genotypic ratios of F1. White color and shortness are the recessive alleles.
Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. What is the percent probability of obtaining a yellow or blue parakeet when a heterozygous green parakeet is crossed with a white parakeet? Show all work including Punnett square and explanation. Record your answer as a whole number rounded to one decimal place.
Solve the following genetic problems involving monohybrid crosses. You must pick the right letter to represent the gene in the question. You must showW your work using the Punnett square. 1. In pea plants, tall is dominant to dwarf. What are the phenotypic ratios of the offspring when a tall plant heterozygous for height is crossed with a dwarf plant? 2. Crossings between pea plants produced the following results. What is the genotype of the parents of each cross? a. Tall x Tall produced 95 tall, 29 dwarf. b. Tall x Tall produced 83 tallI, O dwarf. c. Tall x dwarf produced 73 tall, 0 dwarf.
In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. What will be the phenotypic ratios in the F2? 2. If an F1 plant is backcrossed with the bitter, yellow-spotted parent, what phenotypes and proportions are expected in the offspring? 3. If an F1 plant is backcrossed with the sweet, non-spotted parent, what phenotypes and proportions are expected in the offspring? 4. In cats, curled ears (Cu) result from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1…
