Traits and Reproduction Review

Front

What is selective breeding?

Back

Selective breeding is the process by which humans breed plants or animals for specific traits by choosing which individuals will reproduce.

Front

What are recessive traits?

Back

Recessive traits are characteristics that are expressed only when an individual has two copies of the recessive allele.

Front

What are dominant traits?

Back

Dominant traits are characteristics that are expressed when at least one dominant allele is present.

Front

What are alleles?

Back

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

Front

How does natural selection work?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of proteins in determining traits?

Back

Proteins are essential molecules that perform various functions in organisms, including determining physical traits based on the genes expressed.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles for a trait.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, specifically the alleles present for a particular gene.

Front

What is the significance of camouflage in animals?

Back

Camouflage helps animals blend into their environment, making it harder for predators to spot them, thus increasing their chances of survival.
