Questions & Step-by-Step Solutions

If a purebred red flower (RR) is crossed with a purebred white flower (rr), what will be the color of the flowers in the F1 generation?
  • Step 1: Identify the genotypes of the parent flowers. The red flower is RR (homozygous dominant) and the white flower is rr (homozygous recessive).
  • Step 2: Understand that R (red) is dominant and r (white) is recessive.
  • Step 3: When crossing RR with rr, each parent contributes one allele to the offspring.
  • Step 4: The red flower (RR) can only contribute R alleles, while the white flower (rr) can only contribute r alleles.
  • Step 5: Combine the alleles from both parents. The offspring will have the genotype Rr.
  • Step 6: Since R is dominant, the phenotype (observable trait) of the flowers in the F1 generation will be red.
  • Mendelian Genetics – Understanding dominant and recessive traits in inheritance patterns.
  • Genotype vs. Phenotype – Differentiating between the genetic makeup (genotype) and the observable characteristics (phenotype) of an organism.
