Concordance: This is a term used in genetics. This term is used to imply the presence of the same trait/characteristic in both the members of a pair of twins.
Twins can be of 2 types. They are monozygotic twins and Dizygotic twins.Monozygotic twins are identical twins, i.e. they are formed from one zygote that later splits into two forming two embryos.
Dizygotic twins are non-identical twins or fraternal twins formed from the fertilization of two different eggs with two different sperm cells.
Concordance values can be calculated as:
C = Number of concordance pairs/(number of concordant pairs + number of discordant pairs)
Monozygotic twins generally have a concordance value of 44% for a specific trait.
Dizygotic twins have a concordance value of less than 5 % for a trait.
For identical twins the number of concordant pairs would be 50 out of 100.concordant pair would be
For non-identical twins, the number of concordant pair would be 17 out of 100.
For a recessive trait to be expressed, both the parents should be heterozygous for that trait.
