Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

Orthologous genes are duplicated genes as an accompaniment to speciation. They are duplicated genes that have lost their function.

		The 1st statement is True and the 2nd statement is False.
		The 1st statement is False and the 2nd statement is True.
		Both Staments are True.
		Both statements are False.

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.

The formation of polyploids is common in plants and can abruptly produce a new species. This is an example of a. allopatric speciation. c. sympatric speciation. b. parapatric speciation. d. all of the above.
Which of the following is least likely to be a process associated with sympatric speciation? A.) specialization on different food resources B.) specialization on different habitats C.) mutations that cause differences in pheromones D.) mutations that cause changes in ploidy
What is a reason that speciation can occur? Organisms within a species are brought into closer proximity by a physical barrier. Organisms within an ecosystem make adaptions that involve different breeding times or interactions. Organisms develop traits that are not beneficial to their survival, and these traits are passed from generation to generation. Organisms develop traits that are beneficial and pass on the same traits to all future generations within the same species.
