What is monohybrid inheritance?

Monohybrid inheritance refers to the inheritance of a single gene or trait from one generation to the next. This type of inheritance involves the study of the transmission of a single gene from one generation to the next, and how it affects the phenotype of an organism. Monohybrid inheritance is often studied using Punnett squares to predict the possible outcomes of genetic crosses.

Monohybrid inheritance is a term used in genetics to describe the inheritance pattern of a single gene. It is a simplified model of inheritance that assumes that only one gene is responsible for a particular trait. In monohybrid inheritance, each individual has two alleles for the gene, one inherited from each parent. The alleles can be either dominant or recessive. The dominant allele is the one that is expressed in the phenotype, even if the individual also has a recessive allele. The recessive allele is only expressed in the phenotype if the individual has two copies of the allele.

Monohybrid inheritance can be used to predict the genotype and phenotype of offspring from a cross between two parents. The genotype is the genetic makeup of an individual, while the phenotype is the observable characteristics of an individual. For example, if one parent has a dominant allele for brown eyes and a recessive allele for blue eyes, and the other parent has two recessive alleles for blue eyes, then all of their offspring will have brown eyes. This is because the dominant allele for brown eyes will be expressed in all of the offspring, even though half of them will have a recessive allele for blue eyes.

Monohybrid inheritance is a useful tool for understanding the basics of genetics. It can be used to predict the inheritance pattern of a single gene, and it can also be used to understand the relationship between genotype and phenotype.
