What Isolating Mechanism Is Mule Is The Sterile Offspring Of A Horse And A Donkey?

Hybrid sterility: This is a type of a postzygotic isolating mechanism. For example, the mule is a hybrid between a donkey and a horse or pony. The diploid chromosome number in the donkey is 62 and in the horse or pony it is 64. The mule therefore has 63 chromosomes and is infertile.

What type of isolation is mule is the sterile offspring of a horse and a donkey?

postzygotic isolating mechanism
Answer and Explanation: The type of isolation mechanism exemplified by a female horse that can mate with a male donkey but produce a mule that is sterile is a postzygotic isolating mechanism. This mechanism specifically prevents the formation of fertile offspring.

Which type of isolating mechanism is found in mule?

Class-loading Isolation Mechanism
To protect the APIs, Mule 4 uses a custom class-loading mechanism.

Is a mule reproductive isolation?

How is this an example of reproductive isolation? The mule is an example of an infertile hybrid. Even though horses and donkeys can mate and produce healthy offspring, those offspring cannot pass their genetic information down to future generations, so they are a genetic dead-end.

Are donkeys and horses reproductively isolated?

Question: Horses and donkeys can interbreed, but their offspring (mules) are infertile.

When a donkey mates with a horse a mule is produced However mules are sterile This is an example of?

Explanation: Classifying species can be a difficult and particularly gray area. The key to this question, however, is that mules are sterile. This is an example of post-zygotic reproductive isolation.

Which is an example of a Prezygotic isolating mechanism?

Prezygotic mechanisms include habitat isolation, mating seasons, “mechanical” isolation, gamete isolation and behavioral isolation.

Is a Mule an example of outbreeding?

Examples-Mule which is developed by mating Male donkey and female horse. So animal breeding is of two types inbreeding and outbreeding. Outbreeding is of further three types outcrossing, crossbreeding and interspecific hybridization.

What is Active MQ in Mule?

ActiveMQ is an open-source protocol developed by Apache which functions as an implementation of message-oriented middleware (MOM). Its basic function is to send messages between different applications. A messaging system is composed of a JMS Broker (middleware), Queues and Topics, Producers, and Consumers.

What type of speciation is Mules?

Occasionally, it is possible to produce an infertile hybrid, such as a mule, which is created by the mating of a male donkey and a female horse, or a hinny, the product of the less common union between a male horse and a female donkey.

What is behavioral isolation example?

Behavioral isolation occurs when the presence or absence of a specific behavior prevents reproduction from taking place. For example, male fireflies use specific light patterns to attract females.

What is an example of reproductive isolation?

Reproductive Isolation Examples
Two closely related species of fish who live in different habitats not mating. Fruit flies of two different species excreting different pheromones. Fertilization between a tiger and a leopard, creating a zygote that does not develop.

What type of reproductive barrier maintains horses and donkeys as separate species?

Gene flow between horses and donkeys is separated by a post-zygotic barrier called infertile offspring. As the name implies, post-zygotic barriers occur after the zygote (fertilized egg) has been formed. Therefore, donkeys and horses can successfully mate; however, their offspring are infertile.

Which type of barrier to reproduction occurs when a horse and a mule reproduce with each other?

Hybrid inviability – the hybrid doesn’t survive. Hybrid infertility – the hybrid is sterile. For example, a cross between horses and donkeys results in a mule which is sterile.

What happens when a horse and a donkey mate and have offspring?

Mule: The result of a donkey stallion mating with a female horse. Mules tend to have the head of a donkey and the extremities of a horse. Hinny: The result of a horse stallion mating with a female donkey. Hinnies are less common than mules and there might be subtle differences in appearance.

Why are donkeys and horses considered separate species even though they can mate?

For example, when a female horse and a male donkey mate, they produce hybrid offspring called mules. Although a mule, pictured below, is perfectly healthy and can live to a ripe old age, it is infertile and cannot have its own offspring. Because of this, we consider horses and donkeys separate species.

Why does a mating between two mule produce sterile offspring?

Those mismatched chromosomes make it hard to make viable sperm and eggs. So mules are sterile because horse and donkey chromosomes are just too different. But they are alive because horse and donkey chromosomes are similar enough to mate.

What are reproductive isolating mechanisms?

The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing offspring, or ensure that any offspring are sterile.

Is a mule an example of hybrid sterility?

For example, a mule is a hybrid between a female horse and a male donkey, could develop into an adult but fails to develop functional gametes, therefore, is sterile. Hence, Option (D) “Hybrid Sterility”.

What is mechanical isolation example?

Mechanical isolation is very common in plants. For example, flowering plants that do not have the correct shape for a pollinator will not receive a pollen transfer, and will therefore not be fertilized. In this case, the shape is the barrier.

Which is the example of temporary isolation?

Temporal isolation also occurs among closely related animal species. For example, a peculiar form of temporal isolation has been observed between two closely related species of cicadas of the genus Magicicada in the United States. Sexually mature adults of Magicicada tredecim emerge every 13 years, whereas those of M.
