In mathematics, cross multiplication is a process where a variable in an equation is determined by cross multiplying two fractions or expressions. Cross multiplication can be applied also compare fractions by multiplying the numerator of each fraction by the other's denominator.
In mathematics, specifically in elementary arithmetic and elementary algebra, given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.
The method is also occasionally known as the "cross your heart" method because a heart can be drawn to remember which things to multiply together and the lines resemble a heart outline.

A dihybrid cross is a cross between F1 offspring of two individuals that differ in two traits of a particular interest. For example, Mendel took homozygous dominant Round and yellow seeds (RRYY) and crossed it with homozygous recessive wrinkled and green seeds (rryy), the progeny obtained in F1 generation were all round and yellow seed (RrYy). The offsprings were heterozygous for both R and Y gene. The F1 plant has four types of gametes, RY, Ry, rY, and ry. For genes on separate chromosomes, each allele pair shows independent assortment. Thus, by crossing F1, the phenotypic ratio was 9:3:3:1, where 9 is yellow and round seeds, 3 represents round and green seeds, 3 represents yellow and wrinkled seeds and 1 represents green and wrinkled seeds.

Tyndall effect can be defined as the scattering of a beam of light by colloidal particles present in a colloidal solution. This effect can be observed when a fine beam of light passes through a small hole in a dark room. This effect occurs due to the scattering of light by particles of dust or smoke present in the air.
The Tyndall effect can also be observed when sunlight passes through the canopy of a dense forest. In the forest, the mist contains tiny droplets of water which act as colloidal particles dispersed in the air.
