Unit 4 Genetics Review

Front

What does Mendel's Law of Segregation state?

Back

All individuals have two alleles for a gene - one from the father and one from the mother.

Front

What is transgenetics?

Back

Putting a section of genes from one species into another species.

Front

What is selective breeding?

Back

The process of breeding plants or animals for specific traits.

Front

What is a gene?

Back

A section of a chromosome that codes for a specific trait or protein.

Front

Which organisms are more often transgenically altered to produce more desirable species?

Back

Plants.

Front

What is a trait?

Back

A characteristic or feature of an organism, often determined by genes.

Front

What is the role of alleles in genetics?

Back

Alleles are different versions of a gene that determine specific traits.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, represented by the alleles they possess.
