This question has two parts. First, answer Part A. Then, answer Part B. Part A : Guinea pigs can have dark fur (D) or white fur (d), and their coat texture can be rough (R) or smooth (r). The alleles for these traits are located on different chromosomes. A cross was done between two parents that were heterozygous for both traits. What is the parents'genotype? A Ddrr B ddRr C DDRR D DdRr

Part A:The parents' genotype is DdRr. This means that they have one allele for dark fur (D) and one allele for white fur (d), and one allele for rough coat texture (R) and one allele for smooth coat texture (r). Since they are heterozygous for both traits, they have one of each allele for each trait.Part B:To determine the possible genotypes and phenotypes of the offspring, we can use a Punnett square. Since the parents are heterozygous for both traits, we can represent their genotypes as DdRr.The possible genotypes of the offspring are:1. DdRr (dark fur, rough coat)2. Ddrr (dark fur, smooth coat)3. ddRr (white fur, rough coat)4. ddrr (white fur, smooth coat)The possible phenotypes of the offspring are:1. Dark fur, rough coat2. Dark fur, smooth coat3. White fur, rough coat4. White fur, smooth coat
