Ans) 10) B. will display the same phenotype as the rr parent
Explaination:
- Example: When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers. Plants with the genotype rr have white flowers.

PRE-LAB QUESTIONS - Genetics - Lab #9 1. Humans inherit two alleles for every gene. For an example, gene "R" provides the instructions for face shape. The dominant allele for the gene is denoted as R and the recessive allele for the gene is denoted as r. The dominant phenotype is a round face shape and the recessive phenotype is a square face shape. Use this information to answer the questions below: What is the genotype of a homozygous dominant...

In testcross of H_ and hh individuals, you obtain 20 offspring; 10 of these have the dominant phenotype, and 10 have the recessive phenotype. Based on this, the genotype of the H_ individual is a. heterozygous. b. homozygous dominant. c. homozygous recessive d. none of these are correct

12) In peas, the yellow seed color is dominant (YY or Yy) over the green seed color (vy). You have been given a plant that only produces yellow seeds and need to determine if the plant is YY or Yy. Which of the following crosses would be most effective for determining the genotype of your plant? A)your plant x a plant that produces only green seeds B)your plant x another plant with known genotype YY C)your plant x another plant...

In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. a) From this data, can you tell if the round pea parent plant is homozygous dominant or heterozygous? Explain. b) If the round pea parent plant is heterozygous, what is the probability that...
