What is Divergent Evolution?

Back

Divergent Evolution is the process where two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What is the phenotype of the offspring from a cross of A-Brown hair (A) and a-blond hair (a)?

Back

The phenotype of the offspring is 75% Brown Hair and 25% Blond Hair.

Front

What are homologous chromosomes?

Back

Homologous chromosomes are chromosome pairs (one from each parent) that are similar in size and carry genes for the same traits.

Front

Back

Convergent Evolution occurs when unrelated species develop similar traits or adaptations due to similar environmental pressures.

Front

Front

What is a phenotype?

Back

Front

What is a genotype?

Back

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

Front

What is the difference between dominant and recessive alleles?

Back

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

Front

What is natural selection?

Back

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