Mendel's Pea Plant Experiment Quiz
Content Section: Mendelian Genetics
Level 17: (3:a,b) People have long known that the characteristics of living things are similar in parents and their offspring. Whether it’s the flower color in pea plants or nose shape in people, it is obvious that offspring resemble their parents. However, it wasn’t until the experiments of Gregor Mendel that scientists understood how characteristics are inherited. Mendel's discoveries formed the basis of genetics, the science of heredity. That’s why Mendel is often called the “father of genetics.” It’s not common for a single researcher to have such an important impact on science. The importance of Mendel's work was due to three things: a curious mind, sound scientific methods, and good luck. You’ll see why when you read or watch about Mendel's experiments. After viewing your 2 of three quest complete the media form for 5 achievements per quest. Total is 10 achievements for this section.
Choose 2 from the following to complete the quest.
1. Video that explain the terminology of genetics 2. Read the chapter that explains all the terms associated with Mendelian Genetics 3. The powerpoint does a good job showing you how heredity can be understood. Use the Content review form to complete each of the quests please do 2 of the 3 quest. Total achievements 4. |

Level 18 (3:a,b,c) When gametes unite during fertilization, the resulting zygote inherits two alleles for each gene. One allele comes from each parent. The alleles an individual inherits make up the individual’s genotype. The two alleles may be the same or different. As shown in paragraph below, an organism with two alleles of the same type (BB or bb) is called a homozygote. An organism with two different alleles (Bb) is called a heterozygote.
Alleles Genotypes Phenotypes
BB (homozygote) purple flowers, Bb (purple) Bb (heterozygote) purple flowers Bb, (white) bb (homozygote) white flowers. There are two alleles, B and b, that control flower color in pea plants. This results in three possible genotypes. Why are there only two phenotypes?
The expression of an organism’s genotype produces its phenotype. The phenotype refers to the organism’s characteristics, such as purple or white flowers. As you can see from paragragh above, different genotypes may produce the same phenotype. For example, BB and Bb genotypes both produce plants with purple flowers. Why does this happen? In a Bb heterozygote, only the B allele is expressed, so the b allele doesn’t influence the phenotype. In general, when only one of two alleles is expressed in the phenotype, the expressed allele is called the dominant allele. The allele that isn’t expressed is called the recessive allele.

Practice Problems
Before you try to solve the problem sets in the paragraph in the next section please watch the videos that have been posted. You will learn how to set up and use the punnet squares, make predictions on inheritance, what is co-dominance and define sex linked traits.

Mendel's genetics laws still apply today, yet there was no understanding of DNA or chromosomes. So why is his data and findings still relavent in todays high tech science?
