Mendel's Laws of Inheritance Menders Success Menders approach to the study of heredity was effective for several reasons. Foremost was his choice of experimental subject, the pea plant Pisum sativum. Monohybrid Crosses Mendel began by studying monohybrid crosses— those between parents that differed in a single characteristic. The principle of segregation (Mendel's first law) states that each individual diploid organism possesses two alleles for any particular characteristic. These two alleles segregate (separate) when gametes are formed, and one allele goes into each gamete. Furthermore, the two alleles segregate into gametes in equal proportions.The concept of dominance that, when two different alleles are present in a genotype, only the trait of the dominant allele is observed in the phenotype. Multiple-Loci Crosses Dihybrid Crosses In addition to his work on monohybrid crosses, Mendel also crossed varieties of peas that differed in two characteristics (dihybrid crosses).…

Mendel's Law of Segregation states that traits can be inherited independently of other traits. For example, the trait for freckles is not linked to a particular hair color. Dark haired individuals could have freckles, much like light haired individuals could have freckles. In order to investigate this, Mendel crossed pea plant parents and followed 2 distinct (separate) traits to see if they would be inherited together. We can also look at this using corn because corn kernels can be different colors, purple (C) or yellow (c) and also different textures, smooth (T) or wrinkly (t). Crosses that follow the inheritance of two traits are called dihybrid (2 trait) crosses, and they require a much larger Punnett Square. Dihybrid Punnett Squares still follow the same format as a monohybrid Punnett square. For this question, study the dihybrid Punnett Square below, and fill in the missing information, and then answer the following questions: (again case matters when writing the allele letters!)…
QUESTION 4 In Mendel's pea plants, round shape (R) is dominant to wrinkled shape (r), and yellow color (Y) is dominant to green color (y). The alleles for seed shape and seed color sort independently. In the parental generation, Mendel crossed a true-breeding round, yellow-seeded plant with a true-breeding wrinkled, green-seeded plant to create an F1 generation. He then crossed the F1 offspring to eachother to create the F2 generation. What is the probability Mendel would observe F2 plants with round and green seeds?

This problem examines possible biochemical explanations for variations of Mendel’s 9:3:3:1 ratio. Exceptwhere indicated, compounds 1, 2, 3, and 4 have different colors, as do mixtures of these compounds. Aand B are enzymes that catalyze the indicated steps ofthe pathway. Alleles A and B specify functional enzymes A and B, respectively; these are completelydominant to alleles a and b, which do not specify anyof the corresponding enzyme. If functional enzyme ispresent, assume that the compound to the left of thearrow is converted completely to the compound to theright of the arrow.

The “chestnut vs. black” debate Shortly after the rediscovery of Mendel’s pea plant experiments, biologists began investigating whether Mendel’s laws applied to other species, as well. In England, a debate broke out about whether the color of racehorses might be governed by Mendel’s laws. Using the British Jockey Club registry of racehorse pedigrees, biologists made the following observations: 1.A chestnut (red) stallion, when bred to chestnut mares, always produced chestnut foals. 2.Certain black stallions, when bred to chestnut mares, produced only black foals. 3.Other black stallions, when bred to chestnut mares, produced a mix of black foals and chestnut foals. Based on these observations, which is dominant: black or chestnut? 1st step: Test the two hypotheses described below. Draw the Punnett squares of the different combinations of parents (use the alleles C/c for color) one after the other, comparing your results with the observations described above. Hypothesis 1 = chestnut is…
Do the data that Mendel obtained fit his hypotheses?For example, Mendel obtained 315 yellow round, 101yellow wrinkled, 108 green round, and 32 greenwrinkled seeds from the selfing of Yy Rr individuals(a total of 556). His hypotheses of segregation andindependent assortment predict a 9:3:3:1 ratio in thiscase. Use the chi-square test to determine whetherMendel’s data are significantly different from whathe predicted. (The chi-square test did not exist inMendel’s day, so he was not able to test his own datafor goodness of fit to his hypotheses.)
