Genotype Ratio of Monohybrid Cross
In a monohybrid cross, which involves the mating of individuals differing in only one trait, the genotype ratio refers to the proportion of different genetic combinations among the offspring. This ratio is determined by Mendelian genetics principles and can be predicted using Punnett squares or probability calculations.
For example, in a monohybrid cross between two heterozygous individuals (Aa x Aa), where ‘A’ represents a dominant allele and ‘a’ represents a recessive allele, the expected genotype ratio among the offspring is 1:2:1. This means that one-fourth of the offspring are expected to be homozygous dominant (AA), half are expected to be heterozygous (Aa), and one-fourth are expected to be homozygous recessive (aa).
The genotype ratio of a monohybrid cross provides valuable insights into the genetic composition of offspring and serves as a foundation for understanding the principles of genetic inheritance.
Genotype
The genotype refers to the genetic makeup or combination of alleles possessed by an organism. Studying the genotype meaning and genotype ratio helps in understanding the inheritance patterns of traits.
In this article, we will cover the genotype meaning, genotype examples and genotype ratio in detail.
