1st Week of Mendelian Genetics

Front

What is an allele?

Back

An allele is a variant form of a gene that can result in different traits, such as flower color or seed shape.

Front

What are the two types of alleles?

Back

Dominant and recessive.

Front

How is a dominant allele represented?

Back

A dominant allele is represented by a capital letter.

Front

How is a recessive allele represented?

Back

A recessive allele is represented by a lowercase letter.

Front

What is the phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the genotype?

Back

The genotype is the genetic constitution of an individual, specifically the alleles present.

Front

What is Mendel's Law of Segregation?

Back

Mendel's Law of Segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is Mendel's Law of Independent Assortment?

Back

Mendel's Law of Independent Assortment states that alleles for different traits are distributed to gametes independently of one another.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene (e.g., AA or aa).

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a particular gene (e.g., Aa).
