Here are the answers to your questions:
Question 1: In a dihybrid cross HhSs x hhss, how many alleles does a kitten inherit from the mother?
Answer: 2 (The mother can contribute one allele for each of the two traits.)
Question 2: What is the phenotype of a pea with the genotype YYRr?
Answer: Yellow, Round (Because YY indicates yellow peas and Rr indicates round peas.)
Question 3: What is the genotype of a pea with the phenotype green and round?
Answer: yyRr (Green peas must have the genotype "yy" and round peas can be either "RR" or "Rr", so a genotype like "yyRr" fits.)
Question 4: What is the correct phenotypic ratio?
(Note: Without the specific dihybrid cross details, a standard dihybrid cross of AaBb x AaBb typically yields a phenotype ratio of 9:3:3:1 — could you provide more specifics about the traits?)
Answer: The expected phenotypic ratio for a typical dihybrid cross is 9:3:3:1, but the correct answer will depend on the traits you are referring to.
Question 5:
(Note: Without the additional context for the final question regarding the phenotypic ratio, it's hard to provide a specific answer.)
If you are looking for a specific ratio based on question 4, the answers could vary. The common ratios to choose from in the context of dihybrid cross are commonly expressed as:
Answer: 9:3:3:1
If you can provide additional context for Questions 4 and 5, I can assist further!
