Introduction:
Genotype is the genetic makeup of an organism based on single or multiple traits. It helps in deciphering the type of progeny that would be observed in the future generations. The genotype determines the

- a. What type of trait is this? How many genes and alleles are involved? Explain your answer. b. What are the genotypes of the 90 and 100 cm plants respectively in the parental generation? c. What is the possible genotype, or genotypes, of the 95 cm class in the F2? c. What is the possible genotype, or genotypes, of the 95 cm class in the F2?arrow_forwardSolve these problems by listing the given genotypes, test crosses, genotypic and phenotypic ratios. 1. A plant with serrated leaf margins (A^aA^a) is crossed with a plant with smooth leaf margins (A^bA^b). What will be the phenotypic and genotypic ratios if a homozygous plant with serrated leaves is crossed with a plant with wavy leaves? Given: Test Cross: Genotypic Ratio: Phenotypic Ratio:arrow_forwardLet's do one more monohybrid cross. Suppose these is a gene in chickens that controls whether their eggs will be brown or white. Assuming that brown eggs (B) are dominant to white eggs (b), what are all of the phenotypes that would result from a cross between two chickens that are heterozygous for laying brown eggs? To get full credit for this question you will need to:a) List the parental genotypes and phenotypes.b) List the gametes produced by each parent.c) Do a punnet square. You can do this by inserting a 3x3 table. This tool can be found by clicking the waffle shaped icon under the bold "B" on the commands ribbon at the top of your answer box.d) List all of the possible genotype and phenotypes from the cross with numbers.arrow_forward

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?arrow_forwardwhat is the answer to this question with solution of a punnet squarearrow_forward
- Genetics practice questionarrow_forwardpicture shows the results of a cross between a tall pea plant and a short pea plant. Q. What phenotypes and proportions will be produced if a tall F1 plant is backcrossed to the short parent?arrow_forward1) Interpret the value of the interference. 2) Map the genes.arrow_forward
- SCIENTIFIC INQUIRY You are handed a mystery pea plantwith tall stems and axial flowers and asked to determine itsgenotype as quickly as possible. You know that the allele fortall stems (T) is dominant to that for dwarf stems (t) and thatthe allele for axial flowers (A) is dominant to that for terminalflowers (a).(a) Identify all the possible genotypes for your mystery plant.(b) Describe the one cross you would do, out in your garden,to determine the exact genotype of your mystery plant.(c) While waiting for the results of your cross, you predict theresults for each possible genotype listed in part a. Explainhow you do this and why this is not called “performinga cross.”(d) Explain how the results of your cross and your predictions will help you learn the genotype of your mysteryplant.arrow_forwardLinkage and Gene Mappingarrow_forwardPlease show proper explanation and solution for me to understand better.
