Traits and Reproduction (Amplify)

Front

What is a pedigree?

Back

A pedigree is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors, often used to track inheritance patterns.

Front

How many generations are typically shown in a pedigree chart?

Back

A pedigree chart can show multiple generations, often 3 or more, to illustrate inheritance over time.

Front

What is a mutation?

Back

A mutation is a random change to a gene that can result in a new trait.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an individual (e.g., AA, Aa, aa), while phenotype refers to the observable traits or characteristics.

Front

What is an allele?

Back

An allele is a specific form of a gene that provides instructions for making a particular protein molecule.

Front

What does homozygous mean?

Back

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

Front

What does heterozygous mean?

Back

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

Front

What is the probability of offspring being heterozygous from a heterozygous and homozygous parent?

Back

The probability is 50%.

Front

What is fertilization?

Back

Fertilization is the process where a sperm cell and an egg cell combine to form a new organism.

Front

What is a dominant trait?

Back

A dominant trait is a trait that is expressed when at least one dominant allele is present in the genotype.
