Punnett square

My thesis is that genes passed from parent to offspring affect their lives in many important ways. Some dogs are bred especially for hunting. These dogs have to be endurant, fast, strong, and intelligent. Meanwhile a toy dog like a teacup dog has to have none of these traits. A toy dog would not be able to take the place of a hunting dog, their genes are just far to different from one another. my first selected subject would be non heritable traits. Non heritable traits affect my life in many…

using a Punnett grid. Teacher will have students pull out laptops and play the interactive Punnett grid game while the teacher roams the room conducting a formative assessment to see who is struggling with the game. Teacher will have students pair up for the lab. Each student will receive a penny. Teacher will explain the rules of the Punnett grid portrait contest. Teacher will roam the room assisting students and conducting a formative assessment on understanding of creating Punnett squares.…

Gregor Mendel: A Great Scientist Gregor Mendel was a scientist, born in 1822. He lived as a monk for a long time, most of his life. He is said to be “the only one who got it more or less right.” I am going to tell about his main discoveries and life. He published his ideas in 1866, but no one believed his ideas until about 1900, over 15 years after his death. He graduated High school and went to University of Olmütz in 1840 at age 18. His family owned just a small farm, and paid a lot for…

Drosophila melanogaster is also known as the fruit fly. It “has played a central role in developmental biology during the twentieth century”. The fruit fly is considered a model organism for many reasons. Drosophila is low maintenance creatures that are easy to care for. Since they are such a small size, scientists are able to control numerous amounts of the Drosophila melanogaster at any given time. Drosophila reproduces many offspring and the offspring are created in a very fast fourteen-day…

Influential People who contributed to Genetics: James Watson: James Dewey Watson is a Nobel Prize-winning biophysicist and researcher, who is credited with co-discovering the the double-helix structure of the deoxyribonucleic acid (DNA) in 1953 with Francis Crick. Crick and Watson’s first efforts towards learning the structure of the DNA came up with many attempts, but it eventually concluded in the spring of 1953. Their research portrayed the DNA model pulling forth the double-helical…

One reason why we decided to use fruit fly’s for our project is that they share many of the same genetics with humans. “Fruit flies share 75% of the genes that cause disease with humans,” which can help scientists discover new diseases very quickly. (Service) Along with that, fruit flies are very low maintenance creatures. With them being very low maintenance, researchers and scientists can have millions of them at a time to work with. As in our class, we also had large amounts of flies to…

the body. The second type is tetragametic chimerism and this occurs when two separate ova are fertilized by two sperm and produce two zygotes. 1 Discussion Question: Is the Punnett square the only way to determine offspring phenotypes? A phenotype is a noticeable attribute. In my opinion, the Punnett square is the only thing that is able to predict an offspring’s phenotype. For example, scientists want to figure out how one child has a different eye color than his three siblings, his…

Here is the cross between Sepia and Vestigial fruit flies to see the possible phenotypes produced in F2 generation. We are able to see the offspring traits showing normal eyes and normal wings,…

with facts to make it better and believable. Second, I have learned what meiosis is where it starts and ends. Every step that goes on. I Learned where we get are traits from that we can use a Punnett square to get a prediction. Lastly, to see what genetics we get from your parents by using the Punnett square. All the concepts that I learned where with the help of my teachers. I have had many good and bad experiences. One of them is how Mrs.Kavan helped when I was getting bullied and she made…

using a Punnett grid, making the first generation only heterozygous, while making + the dominant trait. The second generation of offspring, however, is affected as the combination can create heterozygous and homozygous offspring, being affected by both phenotypes of + and SE. This is not entirely random, though, since a 3:1 ratio is maintained, with + being the most dominant phenotypes from all tests. The significance of this data is gathered through the chi-squared test. The chi-square test…
