In a genetic cross between a homozygous tall plant with homozygous purple flowers and a homozygous short plant with heterozygous purple flowers, how many short plants will you expect in the F2 generation if you sample 36 individuals? Both tall and purple are dominant.

A researcher at ASU is studying the exotic Unicorn Fairy plant. The plant has three genes of interest with the dominant alleles being T-tall, H=hairy leaves and P=purple flowers. The three genes are located in different chromosomes. A trihybrid plant is crossed with a plant that is heterozygous for T and homozygous recessive for the other two genes. What is the probability of getting offspring that is tall, has hairy leaves and white flowers? 9/64 5/8 8/64 O 3/64 O 3/16

A plant with the genotype AAbb was crossed with one with the genotype aaBB. The F1 plants were testcrossed. If the genes are not linked, the expected genotypic ratio in the offspring of this testcross would be?

A man with red hair (hh) reproduces with a heterozygotic woman (Hh). Does the woman have red hair?  What about their children?  Create a Punnett square and determine the ratio or percentage of their offspring that have red hair. As stated in the discussion of independent assortment and dihybrids above, pea color and coat texture are independent traits in pea plants. Yellow (G) is dominant over green (g) and smooth (W) is dominant over wrinkled (w). What would the phenotypic ratios of the offspring of parents with genotypes GGww and ggwW? Show your work with a Punnett square. Review the information on Labrador retrievers above.  What are the phenotypic ratios of the F1 generation offspring of two dihybrids? Make sure to match the numbers with coat colors (e.g, which number in the ration goes with which color).  Use a Punnett square to determine the ratios and show your work.  Make sure to state the phenotypic ratios.  Finally, what color are the parents? Two other Labradors mate and…

A series of experiments shows that oil content in a diploid grain is influenced by four genes (a through d) with additive alleles. The highest-producing strain has 30% oil content; the lowest has 0%. A plant of unknown genotype has an oil content of 22.5%. What is a possible genotype for this plant (+ - additive alleles)? O at a+ b+ bccdd O at a+ b+ b+ c+ c+ d+ d O a+ a+ b b+ c+ c+ d+ d O aa b+ b c+c d+ d+ O a+ a+ b+ b+ccdd

If a heterozygous F1 Tobacco plant was crossed to an albino plant, what is the expected number of green and white plants in the next generation? (show Punnett square)  A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring? A man that can roll his tongue is heterozygous for the trait marries a woman that cannot roll her tongue. They have a child. The rolling tongue is dominant to not rolling tongue. What is the man’s genotype for tongue rolling? The women? Show the Punnett square for the child’s genotype Give the probability (percent chance) that the child can or cannot roll their tongue. Oh no! The F1 and F2 generation seed packet labels were mixed around. How would we know which seeds we planted by observing the color of the leaves? (Hint: What are the genotypes of the two generations? What color leaves do they produce in what ratios?)

Let R = Red flowers and r = white flowers, and T = tall plants and t = short plants. If the uppercase letters represent Mendelian dominant alleles, what is the phenotype of a plant with the genotype rrTt? white flowers, tall pink flowers, tall red flowers, tall red flowers, short white flowers, short

In corn plants, a dominant allele (I) inhibits kernel colour, but the recessive allele (i) permits colour when homozygous. At a different locus, the dominant gene P causes purple kernel colour, and the homozygous recessive genotype pp causes red kernels. If plants that are heterozygous at both loci are crossed, what will be the phenotypic ratio of the F1 generation?

Identify the genotypes of the pea flower plants for each generation P (Guadretieding parents) Phenotypes Purple flowers : Genotypes White flowers 1 2 F1 Gerleyatids) Phenotypes All purple flowers : Genotypes 3 Self- or cross-pollination F2 Generation Phenotypes Purple flowers : Genotypes White flowers 4

Two true breeding plants are cross pollinated. One plant is homozygous dominant for heightand color while the other is homozygous recessive for height and color. (A:tall, a:short, B:brown,b:red) The F1 plants are allowed to self-fertilize to produce an F2 generation. After conductingan experiment we get the following results:398 tall and brown plants122 tall and red plants128 short and brown plants45 short and red plants Using the Chi Square formula and table, determine if your results support the hypothesis ofindependent assortment or not. Show your work. You don’t need to show your Punnett Squaresif you include a statement as to how you figured out the appropriate phenotypic ratio for the F2generation. Round to 1 decimal.4a. What possible gametes can the following individual make: AaBb4b. What possible gametes can the following individual make: AaBbCC
