Question
7. In sexually reproducing organisms, why are there exactly two chromosomes in each homologous pair? 8. Mendel's model consists of four concepts. Describe each concept in the appropriate space below. Mendel's Four Concepts Description of Concept First concept Second concept Third concept Fourth concept (law of segregation) 9. In the third concept of Mendel's model, he explains that the determines the organism's appearance if the two alleles at a locus differ while the has no noticeable effect on the organism's appearance. We will use shorthand to indicate dominant and recessive alleles in working genetics problems. So many of our students make mistakes on problems because of their handwriting. Our advice is to use uppercase block print for dominant alleles (A) and lowercase script (a) for recessive alleles. Always begin each problem by writing out a "key" to the symbols you use. For a cross using purple and white flowered peas, this would be: P = purple flowers p = white flowers
