Science at a Distance Mendelian Genetics Solving Genetic Problems What is a Genetic Problem? A genetic problem is a type examination question that involves both a knowledge of Mendel's experiments, and an analysis of data produced during one of his genetic crosses. In the question the solver is presented with information concerning the genotypes and phenotypes of individuals involved in a genetic cross, and the genotypes and phenotypes of their offspring. Some of this critical information is missing, and the solver's task is to supply that missing data. Example #1 .... A red flowered plant is fertilized with pollen from a plant of unknown phenotype. 62 seeds are collected, planted the next year and grow into the F1 offspring. 16 of these offspring have white flowers and the rest have red flowers. What was the phenotype and genotype of the unknown parental plant? The Four Steps Almost all the genetic problems used in Core Biology 8.1 can be analyzed and solved using four basic steps, or processes.

Login Mendelian Genetics Gregor Mendel was a monk who, in the 1800s, studied the inheritance patterns in strains of garden peas (Wilson, 2000, 137). The importance of his work was not recognized until well after his death, but a whole field of genetics is now named after him, and his early studies lay the basis for the study of genetic inheritance. Between 1856 and 1863, Mendel grew and tested over 28,000 pea plants (biopoint.com, 2004). His carrying out his experiment using peas was fortuitous because they have a relatively simple genetic structure, and their breeding could be controlled so that he could be sure of the parents of his plants. He only measured absolute characteristics such as size, shape, and color, and he used large sample sizes. Mendel's numerical recording of his results and statistical analyses gave credibility to the results he obtained. By examining several successive generations of plants, he was able to develop his first and second laws of inheritance. Mendel's law of segregation has four parts: alternative versions of genes give rise to variations in inherited characteristics; for each character, an organism inherits one gene from each parent; if two alleles differ, the dominant one will be fully expressed in the organism's appearance; and the two genes for each character separate during gamete production (biopoint.com, 2004). Mendel's law of independent assortment is that genes for different traits separate independently during phenotype is thei

Example: Bb homozygous term used to describe a genotype consisting of two alleles which are the same. Example: bb dominant Term used to describe a genotype which contains one or both alleles of a gene whcih is always expressed if present. Dominant alleles are expressed with a capital letter. Example: Rr or RR recessive Term used to describe a genotype in which the alleles inherited from both parents would not be expressed unless they were both present. Recessive alleles are represented by a lower case letter. Example: rr genotype The genetic makeup of an organism. This is represented by capital and lower case letters. One letter indicates the allele inherited from the female parent and one letter represents the allele from the male parent. Example: BB, Bb, bb

Box 644234 Pullman, WA 99164-4234 Voice: (509) 335-5591 Fax: (509) 335-1907 omoto@wsu.edu INTRODUCTION A Macintosh computer program written in Director 5.0 which uses the genetics of parakeet is available for downloading MATERIALS FOR THE EXERCISE The main materials for this exercise are sets of pedigree charts. We also use a coin and a marker pen which students can provide. The pedigree charts already have the circles and squares connected by lines. Each group of 3-5 students is provided with pedigree charts; one "genotype" chart and several blank "phenotype" charts. The genotype chart has the genotype of select individuals noted ( Fig. 1a and Fig. 3 ) and whether the trait to be simulated is dominant, recessive, or sex-linked recessive. The phenotype charts have the same number and orientation of squares and circles connected by lines but are otherwise blank. The exercise involves filling in the genotype chart by tossing a coin to determine which of the two alleles is inherited by an offspring. Thus the exercise simulates nature; each offspring is a result of random choice of one of the two copies of the gene in each parent. Instructors can make their own pedigree charts. One can make a blank pedigree chart using as a guide the pedigree charts on

- Mendelian Genetics - 5 pts. A gene is a unit of heredity on a chromosome and can have alternate forms called alleles. In sexually reproducing organisms each parent contributes one allele to their offspring that may or may not be like the other parent's allele. Alleles for a particular gene occur in pairs. Alleles that mask expression of other alleles of a particular gene, but are themselves expressed are dominant, and are usually designated by a capital letter (for example, "B"). Alleles whose expression is masked by dominant alleles are recessive, and are designated by a lower case letter (for example, "b"). The genotype of an organism includes all the alleles present in the cell, whether they are dominant or recessive. The Biochemical manifestation of the trait is called the phenotype. Monohybrid Cross of Corn - A monohybrid cross begins with experimental breeding between two parents that breed true for different forms of a single trait. The trait you will investigate in this problem is kernel color. The two forms of kernel color we will look at are Blue and Yellow. Corn is a good organism for this type of analysis since each grain (kernel) represents an independent offspring. We start with a plant homozygous for blue kernels and cross it with a plant homozygous for yellow kernels. The offspring that result from this cross are called hybrids and are the
