98 points! need in guinea pigs, dark hair (d) is dominant over light hair (d) and curly hair (c) is dominant over smooth hair (c). complete a dihybrid cross for parents with the genotypes: ddcc × ddcc and answer the following in complete sentences. describe how you would set up a punnett square for this cross.

The Punnett square is a tool for predicting the possible genotypes of offsprings from different parents. In this case, the square should be a table of rolls and columns. The rolls are the possible alleles of one of the parents and the columns are the possible alleles of the other parent, which will be the same as both have the same genotype. The possible alleles for both parents would be: DC, Dc, dC, and dc. On the actual table's entries, all alleles should be crossed from one entry and the other obtaining the possible genotypes of the offspring and their proportions, and, therefore, the possible phenotypes and their proportions.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
