Problemas

In pea plants, the allele for tall plants (T) is dominant,over short plants (t), and the allele for purple flowers (P) is dominant over white flowers (p). A plant heterozygous for both traits (TtPp) is crossed with a plant that is short and has white flowers (ttp). What is the probability that the offspring will be tall with white flowers? Hint: make the punnett square! A) 25% B) 50% C) 75% D) 100%

To solve this problem, we need to use a Punnett square to determine the probability of the offspring being tall with white flowers.Given information:- The allele for tall plants (T) is dominant over short plants (t).- The allele for purple flowers (P) is dominant over white flowers (p).- A plant heterozygous for both traits (TtPp) is crossed with a plant that is short and has white flowers (ttpp).Step 1: Determine the possible genotypes of the parents.Parent 1: TtPp (heterozygous for both traits)Parent 2: ttpp (short and white flowers)Step 2: Create a Punnett square to determine the possible genotypes of the offspring.| | T | t | P | p ||-------|-----|-----|-----|-----|| t | Tt | tt | Pp | pp || p | Tp | tp | Pp | pp |Step 3: Calculate the probability of the offspring being tall with white flowers.From the Punnett square, we can see that there are 4 possible genotypes for the offspring:1. TtPp (tall with purple flowers)2. Ttpp (tall with white flowers)3. ttPp (short with purple flowers)4. ttpp (short with white flowers)Out of these 4 genotypes, only 1 (Ttpp) results in the offspring being tall with white flowers.Therefore, the probability of the offspring being tall with white flowers is 1 out of 4, or 25%.The correct answer is A) 25%.
