c) Falconer's equation, Law of Segregation, Law of Independent Assortment
d) Falconer's equation, Intraclass Correlation, Law of Segregation

Answer 1

The three equations you need to know to solve problems about heritability using twin studies are Falconer's equation, Intraclass Correlation, and the Law of Segregation.

Step-by-step explanation:

The three equations that you need to know in order to solve problems about heritability that use twin studies are:

1. Falconer's equation: This equation is used to calculate the heritability of a trait based on the correlation between twins. It is expressed as:
`H = 2(rMZ - rDZ)`, where H is the heritability, rMZ is the correlation coefficient of monozygotic twins, and rDZ is the correlation coefficient of dizygotic twins.

2. Intraclass Correlation: This is another equation that measures the similarity between twins. It is used to estimate the genetic component of a trait by comparing the within-pair correlation of monozygotic twins to the within-pair correlation of dizygotic twins.

3. Law of Segregation: This law states that during the formation of gametes, the two alleles for a trait separate and go into different gametes. This is important in understanding how traits are inherited from parents to offspring.
