What are the Reproductive Barriers that keep species separate?
stiv31 [10]

Answer:

C. habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation.

Explanation:

Reproductive Barriers may be of any type which includes habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation. All these examples are categorized under prezygotic barriers.

Habitat isolation: It occurs in case of allopatric speciation, initially all the members of a species can mate with each other but later on due to geographic barriers like due to a rift, their habitat separates and they cannot mate with each other and later on they evolve as separate species.

Temporal isolation: In temporal isolation, reproductive barrier is different time/season of breeding like American toads and Fowler's toad both are closely related and have potential to mate but due to different mating season they are unable to mate with each other. American toads mate during summers while Fowler's toad mate during late summers.

Behavioral isolation: When the members of two closely related species behave and respond to different mating behavior, it is known as behavioral isolation. For example breeding calls.

Mechanical isolation: Mechanical isolation occurs because of structural or chemical barriers. For example: when the shape of pollinator does not match with that of flower then the male gametes will not be able to reach to the egg cell.

Gamete isolation: When the gametes are unable to fuse due to any reason like less mobility of sperm in the female reproductive tract.

Identical twins Brody and Brady both demonstrate high levels of Agreeableness and Openness, compared to their fraternal twin fri
seropon [69]

Answer: a) genetic

b) environmental

Explanation:

Phenotype is a function of genotype and environment

P=G+E

Where P= phenotype

G=Genotype

E=Environment

The phenotype of an individual i.e what is seen or expressed is a product of the gene he or she carries and the environment they occupy.

Gene is the genetic makeup of an individual.

The Identical and fraternal twin are products of their gene and the environment such as uterine environment, parenting style they grow, Identical twins have 100% of identical genes while fraternal twin have 50% gene in common

Hence, the difference is a function of their genetic makeup and the environment they grow.

Culture and evolution can also be regarded as part of the environment.
