Cross mating, also known as crossbreeding, refers to the practice of breeding animals from different breeds or genetic lines to promote desirable traits in their offspring. This technique is commonly used in agriculture and animal husbandry to enhance characteristics such as growth rate, disease resistance, and reproductive performance. The goal is often to produce hybrid vigor, where the resulting offspring exhibit improved qualities compared to their parents. Cross mating can also apply to plants, where different varieties are bred to achieve specific traits.
A mating that considers one pair of contrasting traits is called a monohybrid cross.

Cross breeding means the production of an organism by mating two different species, breeds or varieties together. It can also be referred to as hybridization.
Any offspring resulting from the mating of two distinctly homozyous individualsIn biological terms genetic cross refers to the offspring of sexual reproduction.
A tigon is bred by mating a male tiger with a female lion. The opposite cross, mating a male lion with a female tiger, results in a liger.
The genotypic ratio for a cross refers to the ratio of different genetic combinations that can result from the mating of two individuals. It is typically represented in terms of the different possible genotypes that can be produced.
Cross breeding involves mating two unrelated individuals from different breeds or populations to produce offspring with a mix of traits. Inbreeding involves mating individuals that are closely related, such as siblings or parent-offspring, which can lead to an increase in genetic defects or expression of negative traits due to the lack of genetic variation.
A monohybrid cross considers one pair of contrasting traits (or alleles) in an offspring resulting from the mating of individuals that differ in only one trait. This type of genetic cross allows predictions about the inheritance pattern of a specific trait based on the known genotypes of the parents.
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.
