Monozygotic Twins
Monozygotic Twins are twins that develop from one zygote that splits and forms two embryos, also known as identical twins, sharing nearly 100% of their genetic material.
Dizygotic Twins
Also known as fraternal twins, are siblings born at the same time as a result of the fertilization of two different eggs by two different sperms.
Genes
Units of heredity made up of DNA that are responsible for the inherited characteristics in living organisms, dictating the development and functioning of organisms.
- Interpret the concept of heritability and understand the strategy for its computation.
