Biology Honors Notes 9-2 ; Wandy Pascoal Genotype and Phenotype Genotype is the genetic makeup of an organism, it consists of alleles that the organism inherits from its parents The appearance of an organism, as a result of genotype, is phenotype. Human phenotypes can be altered by behavior When both alleles of a pair are alike the organism is homozygous for that characteristic an organism may be homozygous dominant or homozygous recessive When two alleles in the pair are different the organism is called heterozygous Probability likelihood that a specific event will occur. It may be expressed as a decimal, percentage or a fraction FOR EXAMPLE: in Mendel's experiment the dominant trait of yellow seed color appeared in the F2 generation 6022 times. Total number of individuals was 8023 (6022+2001) 6022/8023=0.75 = 75% The probability that the dominant trait will appear

    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.
