Mendel developed a hypothesis to explain these results that consisted of four related ideas. We will explain each  idea with the modern understanding of genes and chromosomes. 1. Alternative versions of genes account for variations in inherited characters. o The gene for flower color in pea plants exists in two versions, one for purple flowers and one for white flowers. o These alternative versions of a gene are called  alleles. o Each gene resides at a specific locus on a specific chromosome. o The DNA at that locus can vary in its sequence of nucleotides. o The purple-flower and white-flower alleles are two DNA variations at the flower-color locus. 2. For each character, an organism inherits two alleles, one from each parent. o A diploid organism inherits one set of chromosomes from each parent.

    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.
