Cross

From WikiMD's Food, Medicine & Wellness Encyclopedia

Cross is a term used in various fields of study, including genetics, religion, and mathematics. In genetics, a cross refers to the mating of two organisms. In religion, the cross is a symbol representing the crucifixion of Jesus Christ. In mathematics, the cross product is a binary operation on two vectors in three-dimensional space.

Genetics[edit | edit source]

In genetics, a cross or mating is a deliberate process of combining different varieties of organisms to create a hybrid. This is often done to study the results of genetic recombination, or to breed organisms with desirable traits.

Types of Crosses[edit | edit source]

There are several types of crosses in genetics, including:

  • Monohybrid cross: A cross between two individuals differing in a single trait.
  • Dihybrid cross: A cross between two individuals differing in two traits.
  • Test cross: A cross between an individual with an unknown genotype and an individual with a known genotype, usually homozygous recessive.

Religion[edit | edit source]

In Christianity, the cross is a symbol representing the crucifixion of Jesus Christ. It is a central symbol in Christian iconography and worship.

Types of Crosses[edit | edit source]

There are several types of crosses in Christian iconography, including:

  • Latin cross: The most common type of cross, representing the cross on which Jesus was crucified.
  • Greek cross: A cross with arms of equal length.
  • Celtic cross: A cross with a ring surrounding the intersection of the arms and stem.

Mathematics[edit | edit source]

In mathematics, the cross product or vector product is a binary operation on two vectors in three-dimensional space. It results in a vector that is perpendicular to both of the original vectors.
