A daughter gets an X chromosome from her mother and an X chromosome from her father. Suppose the X chromosome from her mother has the gene for normal blood clotting. Suppose the X chromosome from her father has the gene for hemophilia.
By Kardi Teknomo, PhD. A matrix is orthogonal if the transpose is equal to its inverse, that is. Since computing matrix inverse is rather difficult while computing matrix transpose is straightforward, orthogonal matrix make difficult operation easier. Orthogonal matrix is important in many applications because of its properties. Example:
Definition of orthogonal. 1  1a : intersecting or lying at right angles In orthogonal cutting, the cutting edge is perpendicular to the direction of tool travel.b : having perpendicular slopes or tangents at the point of intersection orthogonal curves.
