Correct answer: D. Multiple alleles and co dominance
- A. Multiple alleles and incomplete dominance
- B. Co dominance and incomplete dominance
- C. Incomplete dominance only
- D. Multiple alleles and co dominance
Explanation

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
