Mendel used monohybrid crosses to study the inheritance of pea plant characteristics. In one of his classic experiments, Mendel crossed a purple-flowered plant with a white-flowered plant. All of the offspring plants produced purple flowers. 1. Using the symbols P for the purple allele and p for the white allele, provide the following information:
A. What the genotypes of the Parental Generation plants?
Purple parent: White parent:
B. What is the genotype of the F1 generation?
C. Organisms with two copies of the same allele are called
D. Organisms with two different alleles are called
2. When is it necessary to perform a test cross?
3. In rabbits, brown coat (B) is dominant to white coat (b). A rabbit breeder wants to know the genotype of his best looking male brown rabbit using a test cross. He has brown females and white females available to conduct his breeding experiments.
A. What should be the coat color of the female he must use in this test cross?
B. If the test cross produces seven (7) brown rabbits and one (1) white rabbit, what is the genotype of the brown male rabbit?
4. How is Mendel's Law of Independent related to the events of Meiosis?
5. In your own words, state the Law of Segregation
There are other patterns of inheritance that require explanations beyond the predictions of Mendel's Law of Dominance and Segregation. These patterns are known in biology as non-Mendelian inheritance and include:.
A. Incomplete dominance
B. Codominance
C. Multiple Alleles
D. Pleiotropy (explained in the first assigned video)
E. X-linked inheritance
F. Epistasis
6. Write in the space provided the type of non-Mendelian inheritance from the list above that matches the descriptions or the examples listed below:
1. When a gene has more than two allele variants.(Example)
2. When a single gene or allele controls the expression of 2 or more traits.
3. When offspring show a blended phenotype, a physical appearance intermediate to the phenotype of both parents
4. When an allele is carried in the X chromosome.
