Understanding the Genotype of the Parental Generation in a Monohybrid Cross

The Genotype of the Parental Generation

For the monohybrid cross, the genotype of the parental generation is typically represented by a homozygous dominant individual (AA) and a homozygous recessive individual (aa).

Final answer:

The genotype of the parental generation in a monohybrid cross is typically represented by a homozygous dominant individual (AA) and a homozygous recessive individual (aa).

Explanation:

In a monohybrid cross, the genotype of the parental generation refers to the alleles they possess for the specific trait being studied. The parental generation is typically represented by two individuals, one with a homozygous dominant genotype (AA) and the other with a homozygous recessive genotype (aa).

For example, if we are studying the inheritance of flower color in pea plants, the parental generation could consist of a plant with red flowers (RR) and a plant with white flowers (rr). The red flower color is determined by the dominant allele (R), while the white flower color is determined by the recessive allele (r).

When these two individuals are crossed, their offspring in the F1 generation will all have a heterozygous genotype (Rr) for the flower color trait. This is because each parent contributes one allele to the offspring, resulting in a combination of dominant and recessive alleles.
