When Mendel crossed together two contrasting homozygous individuals, the phenotype of the hybrid in the F1 cross appeared to be that of:
Correct answer: B. Dominant parent
- A. Recessive parent
- B. Dominant parent
- C. Indifferent
- D. Half dominant & recessive
Explanation
Dominant parent is correct. When Mendel crossed two contrasting homozygous individuals, all the offsprings of G1 generation were of dominant phenotype. For example, crossed between round and wrinkled seeded plants produced plants with round seeds in F1 generation.STB- Pg 184.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
