- According to the first video, what happened to Mendel’s papers after he died? To what common theory of the time does the white squirrel/black squirrel example refer? Why was Mendel lucky in his choice of subjects for his studies? What three important conclusions did Mendel arrive at? What is the Mendel-Fisher controversy about? https://www.youtube.com/watch?v=GTiOETaZg4w&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=2
- Based on the second video, what is the gene theory all about? In the many experiments Mendel performed, how was he able to physically control mating? How did he arrive with his true-breeding parent pea plants? What process was he performing when he bred true-breeding purple flower plants with true-breeding white flower plants? https://www.youtube.com/watch?v=3f_eisNPpnc&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=3
- In the second video, what two Mendelian Laws are discussed? In some up, briefly describe what each law means using the experiment from the video that illustrates these two laws. How did the experiment affect the hypothesis of blending? https://www.youtube.com/watch?v=y4Ne9DXk_Jc&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=4
- In the second video, which pea plant traits were found to be dominant? Which were found to be recessive? What term does the video use to describe the physical characteristic of a trait, such as a purple flower or wrinkled seed? How is that term different from genotype? https://www.youtube.com/watch?v=y4Ne9DXk_Jc&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=4
- The second video uses the terms homozygous and heterozygous when describing the genotype. What do the terms mean, and what happens if two homozygous individuals are mated together? What happens if two heterozygous individuals are mated together? What happens if one of each is mated together? https://www.youtube.com/watch?v=y4Ne9DXk_Jc&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=4
- In the fourth and fifth videos, what type of non-Mendelian inheritance results in pink flowers in the F1generation from red and white true-breeding parents? How is the pink trait created? What example(s) is/are given in the video for codominance? What is epistasis and how does it affect the expression of a trait? https://www.youtube.com/watch?v=-EmvmBuK-B8&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=5&t=436s
- Describe an example used in the sixth video to explain sex-linked inheritance. If a recess trait is carried on the X chromosome, who is more likely to express the recessive trait, males or females? Why? Are any traits carried on the Y chromosome? Sex-linked https://www.youtube.com/watch?v=h2xufrHWG3E&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=7
- Videos 7 and 8 describe the two Mendelian Laws of inheritance. What are these two laws? How did Mendel arrive at these conclusions? Does all traits follow these laws? Why or why not? https://www.youtube.com/watch?v=-FJWTDqlvbU&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=9
- In video 9, what two scientists proposed the chromosomal theory of inheritance and how does it build on Mendel’s original findings? What does this theory help explain that Mendel’s laws did not? How were the two scientists able to describe what Mendel could not? https://www.youtube.com/watch?v=rV6O3rGulaY&list=PLfQf5Axy67poIW6RZME3c_KE6eqaYeNZP&index=9
- In the last video, what example of a trisomic aneuploidy caused by non-disjunction was discussed? How did this non-disjunction occur? What were some risk factors associated with this non-disjunction? How was the condition diagnosed, and what was the term for the procedure that was used to gather the karyotype?
