What are homeotic genes? correct answers
Genes that determine the identity of body segments and structures.
What are the impacts of homeotic mutations? correct
answers
They can cause organ mutations, change segment identities, and lead to
duplications or failures in regulation.
What is a cis-regulatory element? correct answers
A non-coding DNA sequence that influences the gene it is near.
What is a trans-regulatory element? correct answers
A diffusible molecule, such as a transcription factor, that regulates
genes from a distance.
What factors affect evolvability? correct answers
Genetic variation and heritability.
What is standing genetic variation? correct answers
Genetic variation present in a population before selection acts.

What does P = G/h² represent? correct answers
Phenotypic variance (P) is equal to genetic variance (G) divided by
heritability (h²).
What is pleiotropy? correct answers
When one gene locus affects multiple traits.
What is modularity in genetics? correct answers
The concept that certain traits can evolve independently due to genetic
pleiotropy.
What is phenotypic plasticity? correct answers
The ability of the same genotype to produce different phenotypes in
response to environmental changes.
What is canalization? correct answers
The ability to produce a specific phenotype regardless of environmental
variations.
What is genetic assimilation? correct answers
