What is genetics?

Back

Genetics is the study of heredity and the variation of inherited characteristics.

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific animals or plants to reproduce based on desired traits.

Front

What is a phenotype?

Back

Phenotype refers to the observable physical characteristics of an organism, determined by both genetics and environmental factors.

Front

What is a genotype?

Back

Genotype is the genetic makeup of an organism, representing the alleles inherited from its parents.

Front

What is the difference between dominant and recessive traits?

Back

Dominant traits are expressed in the phenotype even if only one allele is present, while recessive traits are expressed only when two recessive alleles are present.

Front

What does it mean if a trait is recessive?

Back

A recessive trait is one that requires two copies of the allele to be expressed in the phenotype.

Front

What is the role of alleles in genetics?

Back

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

Front

What is a pedigree chart?

Back

A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

What is the significance of environmental factors in genetics?

Back

Environmental factors can influence the expression of genes and affect an organism's phenotype.

What is the purpose of a Punnett square?

Back

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