Meiosis and Genetics Summative

Front

What is incomplete dominance?

Back

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 traits.

Front

What are attached earlobes?

Back

A trait where the earlobes are connected directly to the side of the head, which is a recessive trait.

Front

What percentage of genetic material do offspring inherit from their parents?

Back

50% from each parent.

Front

What is codominance?

Back

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 a dominant allele?

Back

An allele that expresses its phenotype even in the presence of a recessive allele.

Front

What is a recessive allele?

Back

An allele that only expresses its phenotype when two copies are present (homozygous condition).

Front

What are polygenic traits?

Back

Traits that are controlled by multiple genes, leading to a wide range of phenotypes.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable characteristics.

Front

What is the role of chromosomes in genetics?

Back

Chromosomes carry genetic information in the form of genes, which determine traits.

Front

What is the principle of segregation?

Back

The principle stating that during the formation of gametes, the two alleles for a trait separate from each other.
