-Mendel’s principles of inheritance.

 

Mendel’s principles of inheritance: U.S.A

Law of dominance
"uniformity"

Some alleles are dominant while others are recessive; an organism with at least one dominant allele will display the effect of the dominant allele.

Law of segregation

During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele (heterozygous) for each gene.

Law of independent assortment

Genes for different traits can segregate independently during the formation of gametes.

In reality, this is not always true, as genes that are close together on the same chromosome tend to be inherited together, i.e. they are 'linked’.
