What is Non-Mendelian Genetics?

Back

Non-Mendelian Genetics refers to patterns of inheritance that do not follow Mendel's laws of inheritance, including incomplete dominance, codominance, and multiple alleles.

How many pairs of chromosomes do humans have?

Back

Humans have 23 pairs of chromosomes.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two.

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is the phenotype of a plant with genotype RW in incomplete dominance?

Back

The phenotype of a plant with genotype RW in incomplete dominance is pink flowers.

Can a man with type O blood be the father of a type B baby if the mother is type A?

Back

No, a man with type O blood cannot be the father of a type B baby if the mother is type A.

Front

What is the result of crossing a red flowered plant (RR) with a white flowered plant (WW) in incomplete dominance?

Back

The result is 100% pink flowered offspring (RW).

Front

What is the significance of multiple alleles in genetics?

Back

Multiple alleles refer to the presence of more than two alleles for a genetic trait, allowing for a greater variety of phenotypes.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is an example of codominance in animals?

Back

An example of codominance is a calico cat, which shows both orange and black fur.
