Mendelian Genetics Flashcards
What are Mendel’s three laws of inheritance?
Law of Segregation, Law of Independent Assortment and Law of Dominance.
What is ment by Mendel’s first law - Segregation ?
Individuals can pass only one allele for a characteristic onto a gamete.
In a hetrozygote, there will be an equal probability of this being either of their two different alleles.
What is ment by Mendel’s second law - Independent Assortment?
The inheritance of one characteristic will have no effect on the inheritance of another.
This only applies when genes are not linked on the same chromosome.
What is ment by Mendel’s Third Law - Dominance?
Some alleles are dominant over others.
This means that the dominant allele will always be expressed if present in an animals genome.
