- Need help number 10 is the problem solver How many different phenotypes are possible among the offspring ? What is the probability of getting DD offspring ? What is the probability of getting dad offspring ?arrow_forwardNeep help ASAP. A red flowered plant was crossed with a blue flowered plant and produced all purple flowered plants. When the purple flowered plants were crossed with each other they produced 5 red plants, 5 blue plants, 20 deep purple plants, 20 light lilac plants, and 30 purple plants How many genes are involved in the color production? Assume that red color is caused by an A allele and blue color by a B allele and determine the likely genotype of the plants in the F2 generation.arrow_forwardMAKE CONNECTIONS The ABO blood type locus hasbeen mapped on chromosome 9. A father who has typeAB blood and a mother who has type O blood have achild with trisomy 9 and type A blood. Using this information, can you tell in which parent the nondisjunctionoccurred?

Show the cross and provide full justification in each case:a) An F1 x F1 self-fertilization gives a 9:7 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1? b) An F1 x F1 self-fertilization gives a 9:3:4 phenotypic ratio in the F2.

Consider the cross of a true-breeding long-stemmed variety to a true-breeding short-stemmed variety in which long stems are completely dominant. a. If 120 F1 plants are examined, how many plants are expected to be long stemmed? Short stemmed? b. Assign genotypes to both P1 varieties and to all phenotypes listed in (a). c.

- Problem: A homozygous tall, homozygous white flower plant crosses with a homozygous short, homozygous purple flower plant. We know that the purple and tall flowers are the dominant traits. Show your work. What are the phenotypes of the offspring?arrow_forward10. In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele. If you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the F1 individuals? Set up a Punnett square for the dihybrid cross.arrow_forwardIn peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?arrow_forward

In certain breeds of dogs, two different sets of alleles determine the color pattern. Black color is dominant and red color is recessive; solid color is dominant and white spotting is recessive.

In four-o’clock plants, the allele for red flower color has an effect that is incompletely dominant over the effect of the white color allele.
