Mendelian and Non Mendelian traits

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, representing the alleles inherited from both parents.

Front

What are Mendelian traits?

Back

Mendelian traits are characteristics that are determined by a single gene and follow Mendel's laws of inheritance.

Front

What are Non-Mendelian traits?

Back

Non-Mendelian traits are characteristics that do not follow Mendelian inheritance patterns, often influenced by multiple genes or environmental factors.

Front

What is the significance of Gregor Mendel in genetics?

Back

Gregor Mendel is known as the 'father of genetics' for his foundational work on the inheritance of traits in pea plants.

Front

What is the ABO blood group system?

Back

The ABO blood group system classifies human blood into four main types: A, B, AB, and O, based on the presence or absence of antigens.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype and environment.

Front

What is the universal donor blood type?

Back

The universal donor blood type is O, as it can be given to individuals of any blood type without causing an immune reaction.

Front

What is the role of antibodies in the blood?

Back

Antibodies are proteins in the plasma that help identify and neutralize foreign objects like bacteria and viruses.

Front

What does it mean for a trait to be dominant?

Back

A dominant trait is one that is expressed in the phenotype even when only one copy of the allele is present.

Front

What does it mean for a trait to be recessive?

Back

A recessive trait is one that is expressed in the phenotype only when two copies of the allele are present.
