The basis of genetics were established by Gregor Mendel, an Augustinian monk in the mid to late 1800’s. Through the observations from cross-pollinating pea plants, Mendel was able to discover the basic laws of inheritance. Mendel’s experiment was to cross pollinate pea plants and observe how traits were passed on. He started his experiment with two true breeding pods,

The “Brassica rapa” is a fast plant known as the field mustard. This plant is well known for its rapid growing rate, which makes it an easy breeding cycle and easy to pollinate. In giving so this makes “Brassica rapa” a great participant for testing Gregor Mendel’s theories of inheritance. The “Brassica rapa” acts like a test subject in testing cross-pollination giving the understanding to the dominant allele of colored stems. There are different colors that are visible on the stem that are above the soil; the colors vary from green to purple. P1 seed was ordered, germinated and cross-pollinated until germination of the next off spring of plants were also done. It was

He chose to study in detail the common garden pea, Pisum, which he grew in the monastery garden. During 1856 and 1863 Mendel tested his pea plants reaching a number of maybe 28,000 pea plants, carefully examining seven pairs of seeds for comparison, such as shape of seed, color of seed, tall stemmed and short stemmed and tall plants and short plants looking and the differences in the same plant. Johann Mendel worked on this for many years, carefully wrapping each individual plant to prevent accidental pollination by insects. He collected the seeds produced by the plants and studied these seeds observing that some plants. Johann Mendel discovered that by putting together tall and short parent plants he got hybrid result that resembled the tall parent rather than being a medium height blend. He explained his concept of heredity units, now called genes. These often referred to as dominant or recessive characteristics. He then figured out the pattern of inheritance of various and came up two generalizations that became known as the laws of heredity. Johann Mendel's observations led him to coin two terms, which are still used in present-day genetics: dominant and

This discovery was made when Morgan was working at Columbia and one day, while observing a male fruit fly, he noticed that instead having bright red eyes as any normal Drosophila melanogaster would, this particular insect had white eyes. Morgan questioned the cause of the color of that fly to be different and wondered how this trait was acquired. In order to answer his questions, Morgan proceeded to do simple breeding analyses with the white-eye fruit fly. This experiment began with a test cross between the white-eyed fly with normal red-eyed females. The results in the first generation was all red eyes. This was shown through the use of Punnett squares. However Morgan didn’t stop there, he took the male and females from the first generation and test crossed them again. This time, the second generation resulted with some flies with the white-eyed trait along with some red-eyed trait. Morgan noticed that the only white-eyed trait however occurred only in the male fruit flies. This led to his hypothesis of sex-limited, also known as sex-linked. However, upon further experimentations, the next generations of crossing the original male with some first generation red-eyed females resulted with both red-eyed and white-eyed males and females, therefore the trait was concluded to be sex-related and the trait of the coloured-eyed gene was found to be on the X-chromosome. Thus the discovery of how genes are transmitted through chromosomes. In 1933, Thomas Morgan

The variables in this lab were different than the average science experiment. Instead of affecting the experiment to prompt different results, we just had F1 generation plants produce offspring so that we could study their specific traits. By looking at the variables, we can determine if they fit the Mendelian ratio and see if genes are linked on a chromosome.

METHODS/PROCEDURES: In the beginning of the experiment, pea seeds were used in order to perform the experiment. It was extremely important to acquire good, dry, and viable seeds so the process of germination could occur. A handful of these healthy seeds worked best in assisting the experiment. The seeds ability to germinate was a vital information needed to determine the outcome of the experiment.

Gregor Mendel was born in Heinzendorf, Austria on July 22, 1822 to the parents of Rosine and Anton Mendel. Gregor grew up on his families farm until he reached age 11 when a schoolmaster was impressed with his determination for learning and suggested that he should be sent off to secondary school in Troppau. The move all the way from Austria to Troppau was very money straining for the family, but well worth it in the end. In 1840, Gregor graduated from the school with honors. In 1843, he went aganist his fathers orders and decided to become a monk, until he worked so hard that he physically became ill. Due to his illness he was sent to the University of Vienna to expand his studies in science.

In conclusion, Mendel and Curie both had a positive impact on the world of Allied Health. Mendel's work with pea plants contributed to the Allied Health field by giving the fundamental laws of genetics. Radioactivity that Curie helped discovered led to new therapeutic and diagnostic methods in medicine. Mendel's experiments led to a greater understanding of genetics. As you can see, Mendel had a greater impact on society because his laws about genetics affects our crops, our own human genetics and the genetics of

Gregor Mendel was born Johann Mendel on July 22 in 1822. He did not grow up in a predominate family, nor home. His parents were poor farmers and although not wealthy, he was incredibly smart and always excelled in school. At age 11 a local schoolmaster was impressed by Mendel’s school work and aptitude for learning. So much in fact that he recommended sending him to a school in Troppau to continue his

Another man who contributed greatly to the study of genetics, was an American biologist by the name of Thomas Hunt Morgan. He studied the ways that characteristics were passed from one generation of fruit flies to the next. He learned that the genes in fruit flies behaved in the same way as the genes in pea plants. He also noticed that certain genes were inherited together more often than random chance should allow.
