12/6🟢FLASHCARD Punnett Squares

Front

What is the dominant factor in Mendel's genetic cross experiment?

Back

The dominant factor is the Tall factor (T).

Front

What do the letters in the boxes of a Punnett square represent?

Back

The letters represent the possible offspring with one factor from each parent.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genetic makeup of offspring from a genetic cross.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., TT or tt).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Tt).

Front

What is the phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the genotype?

Back

The genotype is the genetic constitution of an individual, represented by the alleles it possesses.

Front

What is the purpose of a test cross?

Back

A test cross is used to determine the genotype of an individual with a dominant phenotype by crossing it with a homozygous recessive individual.

Front

What is an allele?

Back

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

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.
