Inquiry question Mendel did not examine plant height and pod shape in his dihybrid crosses. The genes for these traits are very close together on the same chromosome. How would this have changed Mendel’s results?

Expert Solution & Answer

Summary Introduction

To determine: The process in which the situation has changed the results of Mendel.

Introduction: Mendel experimented on pea plant and selected traits like the height of the plant, position of flower, the color of a pod, form of an unripe pod, the color of the seed coat, color of cotyledons and form of a seed.

Explanation of Solution

Mendel did not examine plant height and pot shape in his dihybrid cross and the Gene's for these lies very close to each other and this can affect the result of Mendel's study. The genes located on different chromosomes assort independently and give the dihybrid ratio of 9:3:3:1 and testcross ratio of 1:1:1:1. In this case, parental type and recombinant type are formed in equal proportion. In the case of linked genes, there will be no formation of recombinants or fewer recombinants will be formed. The dihybrid test will be disturbed.

Summary IntroductionTo determine:Whether the given statement “All traits are inherited in a Mendelian pattern.” is true or false.Introduction:Some traits are transferred to the offspring from their parents; this process is called inheritance. Mendel gave some laws to describe how genetic transmission of traits take place, the inheritance pattern that follows the law of Mendel is known as Mendelian inheritance. Mendel gave the law of segregation, the law of dominance, and the law of independent assortment.

Question:- You are setting up a Mendelian tetra-hybrid (4 gene) cross. What are possible genotypes for the parents?

Question:- For a simple cross between a purple-flowered plant and a white-flowered plant, where purple is dominant over white. a. Show the F2 in a Punnett square. What are the proportions of genotypes and phenotypes? Express as fractions, decimal fractions and ratios. b. Now imagine that half of the pollen carrying the recessive allele die before reaching their target, while those carrying the dominant allele are unaffected; what are the proportions of genotypes and phenotypes now?What does this tell you about Mendel’s principle of segregation?
