Explanation:
When two heterozygous individuals (Aa) for a single trait are crossed, the resulting offspring will have a genotypic ratio of 1:2:1 for the three possible genotypes (AA, Aa, and aa). This is known as a monohybrid outcross.
Genotypic ratio:
In the F2 generation of a monohybrid outcross, the genotypic ratio will be 1:2:1 for the three possible genotypes (AA, Aa, and aa). This is because the F1 generation will have all heterozygous (Aa) individuals, and when they are crossed with each other, the resulting offspring will have a 1:2:1 genotypic ratio.
Phenotypic ratio:
The phenotypic ratio in the F2 generation of a monohybrid outcross will depend on the dominance relationship between the alleles. If the dominant allele (A) completely masks the recessive allele (a), then the phenotypic ratio will be 3:1 for the dominant phenotype (AA and Aa) to the recessive phenotype (aa). If the dominant allele (A) only partially masks the recessive allele (a), then the phenotypic ratio will be 1:2:1 for the dominant phenotype (AA and Aa) to the recessive phenotype (aa).
Overall, the genotypic ratio in the F2 generation of a monohybrid outcross will be 1:2:1 for the three possible genotypes (AA, Aa, and aa), regardless of the phenotypic ratio.
