Set up a punnett square using the following information • Dominant 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)
Answer (1)
To set up a Punnett square for a dihybrid cross between a homozygous dominant (DDWW) and a homozygous recessive (ddww) parent, follow these steps:Step 1: Identify the parent genotypesParent 1 (homozygous dominant) = DDWWParent 2 (homozygous recessive) = ddwwStep 2: Determine the possible gametesParent 1 (DDWW) produces only DW gametes.Parent 2 (ddww) produces only dw gametes.Step 3: Set up the Punnett squareSince each parent can only produce one type of gamete, the Punnett square will be 1x1.DWdw DdWwStep 4: Interpret the resultsGenotype: All offspring will be DdWw (heterozygous for both traits).Phenotype: All offspring will be tall plants with purple flowers because the dominant alleles (D and W) mask the recessive ones.This cross results in 100% tall plants with purple flowers.
