Let's analyze the inheritance of human hair texture. Step 1: Determine the genotypes of the parents. The problem states that wavy hair is produced by the heterozygous genotype (Cc). Since both parents have wavy hair, their genotypes are both Cc. Step 2: Determine the possible gametes for each parent. Each parent (Cc) can produce two types of gametes: C and c. Step 3: Construct a Punnett square for the cross (Cc x Cc). | | C | c | | :-- | :-- | :-- | | C | CC | Cc | | c | Cc | cc | Step 4: Determine the genotypic ratio of the offspring. From the Punnett square, the possible genotypes are: CC: 1 out of 4 Cc: 2 out of 4 cc: 1 out of 4 The genotypic ratio is 1 CC : 2 Cc : 1 cc. Step 5: Determine the phenotypic ratio of the offspring. Based on the genotypes and the given information: CC produces curly hair. Cc produces wavy hair. cc produces straight hair. So, the phenotypes are: Curly hair (CC): 1 out of 4 Wavy hair (Cc): 2 out of 4 Straight hair (cc): 1 out of 4 The phenotypic ratio is 1 Curly : 2 Wavy : 1 Straight. The cross between two parents with wavy hair (Cc x Cc) results in offspring with the following ratios: Genotypic Ratio: 1 CC : 2 Cc : 1 cc Phenotypic Ratio: 1 Curly : 2 Wavy : 1 Straight What's next?
