1st Semester Review Part 3 Mendelian Nonmendelian Inheritance

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygous individual contribute equally and visibly to the phenotype.

Front

What is a phenotype?

Back

The description of the appearance of a trait.

Front

What is a genotype?

Back

The genetic makeup of an individual, represented by the alleles they possess.

Front

What does homozygous mean?

Back

An organism with two identical alleles for a specific trait.

Front

What does heterozygous mean?

Back

An organism with two different alleles for a specific trait.

Front

What is incomplete dominance?

Back

A genetic situation where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is the purpose of a Punnett square?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What are alleles?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is Mendelian inheritance?

Back

The patterns of inheritance first described by Gregor Mendel, including concepts like dominance, segregation, and independent assortment.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even in the presence of a recessive allele, while recessive alleles only express their trait when two copies are present.
