What is an acquired trait?

Back

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

Front

What is an inherited trait?

Back

An inherited trait is a characteristic that is passed down from parents to offspring through genes, such as having blue eyes.

Front

What does homozygous dominant mean?

Back

A homozygous dominant genotype consists of two identical dominant alleles, represented as 'AA'.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, such as blue eyes.

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 refers to the observable traits.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.

Front

What does it mean for a trait to be polygenic?

Back

A polygenic trait is controlled by multiple genes, leading to a range of phenotypes, such as height.

Front

What is the role of DNA in heredity?

Back

DNA carries genetic information that is passed from parents to offspring, determining inherited traits.
