Lab 9 1.Drawing 2 chromosomes the same size and length while carrying genes for the same traits. The colored card represents alleles. One allele is one of the chromosomes in the homologous pair, and the other is in the same location on the other chromosome in the pair. 2. Drawing 1 card of each color and placing all these cards in an “egg” or sperm”; the # of cards in the gamete is half the number you started with. 3. Fertilization is represented by combining the cards in a “sperm” with the cards in an “egg” 4. An individual with a sickle cell trait is a heterozygote; there is an equal chance of passing on the recessive allele. 5. Combining DNA fragments from 2 different sources into one molecule 6. A restriction enzyme recognizes a specific sequence of base in DNA and cuts the DNA at a specific site between nucleotides. Single stranded DNA at the ends f the DNA fragments (“sticky ends”) can stick to complimentary stretches of DNA by base-pairing. 2 fragments of DNA from different sources but cut by the same restriction enzyme will have identical sticky ends and can be spliced together.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
