How is reproductive isolation related to the formation of new species?

∙ 6y ago
Speciation would not be possible without reproductive isolation. We define species today as a group of organisms capable of reproducing fertile offspring. If there was no reproductive isolation, it means that the organisms are constantly interbreeding, mixing their genes, thus unable to become two mutually reproductively exclusive groups, or different species.

What factors are involved in the formation of new species?
reproductive isolation
What Factor is necessary in the formation of a new species?
Reproductive isolation
The taxon species may be defined by reproductive isolation and?
morphology
What are three types of barriers that can lead to reproductive isolation?
The three types of reproductive isolation are: 1. Temporal isolation: different times of reproduction 2. Behavioral isolation: different habits of the same species 3. Geographical isolation: species are separated by natural barriers
5 factors that lead to the formation of a new species?
(i) Absence of gene flow (ii) accumulation of different variations (iii)natural selection (iv) genetic drift (v)reproductive isolation.
What is thought to be essential for the formation of distinct species?
reproductive isolation
What factors are involved in the formation of new species?
reproductive isolation
What Factor is necessary in the formation of a new species?
Reproductive isolation
How is speciation and reproductive isolation related?
Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
What must occur within a gene pool before formation of a new species?
Answer: Reproductive Isolation
What must occure within a gene pool before the formation of a new species?
Answer: Reproductive Isolation
Is reproductive isolation a factor that is necessary for the formation of a new species?
at present ,yes,but hopefully new scientific advancements will improve the situation
What type of isolation mechanism was important in the formation of Galapagos finches species?
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
What is thought to be essential for the formation of distinct species rather than a continnum form one from of life to another?
Reproductive isolating mechanisms are either prezygotic or postzygotic. These mechanisms ensure that species remain distinct in nature.ChaCha!answer
What is the factor used to define a species?
Reproductive Isolation
What are three types of reproductive isolations?
The three types of reproductive isolation are: 1. Temporal isolation: different times of reproduction 2. Behavioral isolation: different habits of the same species 3. Geographical isolation: species are separated by natural barriers
What are the two kinds of reproductive isolation mechanisms that biologists divide?
Temporal isolation-species mating at different times of the year.Behavioral isolation-mating behaviors in two groups of isolated populations change, thus making individuals from the two groups not attracted to each other.Pollinator isolation-some closely related plant species have flowers that attract different pollinators, preventing the two species from inbreeding.Mechanical isolation-when reproductive organs in closely related species change drastically, making it impossible for one species to mate with another.Gametic isolation-when incompatibilities between the sperm and eggs of closely related species keep them from fusing.Hybrid inviability or sterility-when the egg gets fertilized, the resulting offspring may not live (inviable) or it is sterile.
