Mendelian Genetics Review

Front

Who is known as the father of genetics?

Back

Gregor Mendel, an Italian monk/scientist.

Front

What is the genotype for homozygous dominant?

Back

AA

Front

What is an example of a phenotype?

Back

Red hair.

Front

What principle states that homologous chromosomes line up independently during meiosis?

Back

Independent Assortment.

Front

What does the Law of Segregation state?

Back

During meiosis, homologous alleles split up into different gametes.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup (e.g., AA, Aa), while phenotype refers to the observable traits (e.g., red hair).

Front

What is a dihybrid cross?

Back

A genetic cross that involves two traits, each represented by two alleles.

Front

What is crossing over?

Back

The exchange of genetic material between homologous chromosomes during meiosis, increasing genetic variation.

Front

Define allele.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is a homozygous genotype?

Back

A genotype consisting of two identical alleles for a trait (e.g., AA or aa).
