Hybrid breakdown
What can influence gene expression patterns without altering the underlying DNA sequence?
Epigenetic modifications
What can lead to developmental abnormalities in hybrids?
Epigenetic changes
What is the result of allopatric speciation?
Speciation
What can prevent gene flow in a population?
Geographic barriers
What can occur in later generations of hybrids between two species?
Reduced vigor, increased susceptibility to disease, or reproductive abnormalities
What is the primary reason for hybrid breakdown?
Weakening of genetic compatibility
What is an example of a consequence of genetic incompatibilities in hybrids?
Reduced fertility, developmental abnormalities, or decreased survival
What can be a result of conflicts between the genomes of the parent species?
Genomic instability
What is the likely outcome of accumulating deleterious genetic combinations over generations?
Reduced fertility, developmental abnormalities, or decreased survival
What is a possible consequence of hybrid breakdown?
Reduced fitness or viability
What occurs during the passing on of genes from one generation to the next?
Parts of the genetic blueprints may be copied incorrectly
What is the result of genetic mutations in a population?
Some individuals thrive, while others die out
Which of the following is NOT a concept that helps clarify how descent with modification works?
Environmental adaptation
What is the primary driver of evolution in a population?
Individual selection
What is the outcome of natural selection in a population?
Some individuals thrive, while others die out
What is the unit of evolution, according to the Theory of Evolution?
Populations
Learn about the consequences of genomic instability, including chromosomal rearrangements, gene duplications, and deletions, which can disrupt normal development and reproductive processes. Understand how it leads to genetic aberrations and affects fertility and viability in hybrid species.
