This cross involves only one character such as here the character for height.

It is a plant producing peas usually eaten fresh rather than dried. (Pisum sativum)

A cross, with the phenotype of each sex reversed as compared with the original cross, to test the role of parental sex on inheritance pattern is called as a reciprocal cross.

Polygenic inheritance refers to a kind of inheritance whereby a trait is determined by the expression of many genes together.

Visible characteristics of an organism are called phenotype.

This cross involves single trait and law of dominance and recessiveness was the result of monohybrid cross.

Linkage is the tendency of genes that are located proximal to each other on a chromosome to be inherited together during meiosis. It was given by Bateson.

They discovered that genes act by regulating definite chemical events.

Meiosis is a special type of nuclear division which segregates one copy of each homologous chromosome into each new gamete.

A gene that is expressed only when it is present in two copies or if the other copy is missing.

In human males the sex chromosomes are in heterozygous.

It is one of a number of alternative forms of the same gene or same genetic locus.

It is reproduction from the mating of parents who are closely related genetically. Inbreeding results in increased homozygosity.

The role of pedigree analysis is to analyze the pattern of inheritance of a particular trait.

It is a gene pair in a heterozygous condition that are both fully expressed.

Here allele of one gene gene suppresses the activity of an allele of another gene.

The genotype is the genetic make up of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration.

It is a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele.

Law of independent assortment was explained by dihybrid cross involving two traits.
