When Mendel crossed purebred purple flowering planits (PP) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring? 25 percent white and 75 percent purple 50 percent white and 50 percent purple 100 percent purple 100 percent white

To solve this problem, we can use Mendelian genetics principles. 1. **Identify the known conditions:** - Purebred purple flowering plants are represented as \( PP \). - Purebred white flowering plants are represented as \( pp \). - The purple flower color is dominant over the white flower color. 2. **Determine the genotype of the offspring:** - When we cross \( PP \) (purple) with \( pp \) (white), we can set up a Punnett square to visualize the possible combinations of alleles. The possible gametes from each parent are: - From \( PP \): All gametes will be \( P \). - From \( pp \): All gametes will be \( p \). The resulting combinations from the cross \( PP \times pp \) will be: - \( Pp \) (purple) from \( P \) and \( p \). 3. **Analyze the results:** - All offspring will have the genotype \( Pp \), which means they will all express the dominant purple flower color. Thus, the resulting offspring will all be purple flowering plants. The answer is: **100 percent purple.**
