Question
Set up a punnett square using the following information: • Dominate allele for tall plants = D • Recessive allele for dwarf plants = d • Dominate allele for purple flowers = W • Recessive allele for white flowers = w • Cross a homozygous dominate parent (DDWW) with a homozygous recessive parent (ddww) . Using the punnett square find out -a. What is the probability of producing tall plants with purple flowers? Possible genotype(s)?b. What is the probability of producing dwarf plants with white flowers? Possible genotype(s)?c. What is the probability of producing tall plants with white flowers? Possible genotype(s)?d. What is the probability of producing dwarf plants with purple flowers?
Solution
a. The probability of producing tall plants with purple flowers is 100%. The possible genotype is DDWW.
b. The probability of producing dwarf plants with white flowers is 0%. There are no possible genotypes as the dominant parent's genes will always be expressed in the offspring.
c. The probability of producing tall plants with white flowers is 0%. There are no possible genotypes as the dominant parent's genes will always be expressed in the offspring.
d. The probability of producing dwarf plants with purple flowers is 0%. There are no possible genotypes as the dominant parent's genes will always be expressed in the offspring.
This is because when a homozygous dominant parent (DDWW) is crossed with a homozygous recessive parent (ddww), all offspring will inherit one dominant and one recessive allele for each trait, resulting in all offspring being heterozygous (DdWw). Since both height and flower color are controlled by dominant alleles in this case, all offspring will be tall with purple flowers.
