LS.10b-Heredity

Front

What is a recessive trait?

Back

A recessive trait is a characteristic that is expressed only when two recessive alleles are inherited. An example is blue eyes.

Front

How many recessive genes need to be inherited to observe a recessive trait?

Back

Two recessive genes need to be inherited to observe a recessive trait.

Front

What does homozygous dominant mean?

Back

Homozygous dominant refers to having two identical dominant alleles for a trait, represented as 'AA'.

Front

What is an acquired trait?

Back

An acquired trait is a characteristic that is not inherited genetically but developed through experience or environment, such as being good in math.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of two different alleles for a trait, represented as 'Bb'.

Front

What is the difference between genotype and phenotype?

Back

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

Front

What is the role of alleles in heredity?

Back

Alleles are different forms of a gene that determine specific traits in an organism.

Front

What is the significance of dominant traits?

Back

Dominant traits are expressed in the phenotype even if only one dominant allele is present.

Front

What is the Punnett square used for?

Back

A Punnett square is a tool used to predict the genetic outcomes of a cross between two organisms.

Front

What does it mean if an organism is homozygous?

Back

An organism is homozygous if it has two identical alleles for a specific trait.
