What is gametic incompatibility?

Gametic incompatibility is the inability for a sperm to penetrate and fertilise the egg. For example, in abalones, the sperm carries a lysin protein that dissolves a hole in the egg's envelope, but only in eggs from the same species of abalone (D.J. Futuyma, Evolutionary Biology, 1998)


Is a congenital disorder the same as a gametic disorder?

No. A gametic disorder is one that results from an absent or defective gene. A congenital disorder is caused by incidents at birth such as starvation of oxygen after an umbilical cord is wrapped around the newborn's neck. This can cause defects such as Cerebral Palsy. A few examples of a gametic disorder are cystic fibrosis and hemophilia.


What kind of organisms exhibit gametic meiosis?

Organisms that exhibit gametic meiosis are typically animals, including most vertebrates and invertebrates. In this type of meiosis, only the gametes (sperm and egg cells) are haploid, while the rest of the organism's cells are diploid.


What are some non examples of community biology?

Mathematics, computer science, and physics are examples of fields that are not considered community biology. Additionally, studying individual organisms in isolation, without considering their interactions within a community, would also be a non-example of community biology.


How many chromosomes would a tetraploid potato gametic cell contain?

A tetraploid potato cell would contain four sets of chromosomes, so a gametic cell would contain half that amount, which is two sets (diploid). This means a tetraploid potato gametic cell would contain 48 chromosomes.

What are five reproductive barriers?

Five reproductive barriers are habitat isolation, temporal isolation, gametic isolation, hybrid breakdown, and reduced hybrid fertility. Habitat isolation, temporal isolation, and gametic isolation are examples of prezygotic reproductive barriers, meaning that they impede mating or hinder fertilization if mating does occur. Habitat isolation: Even if two species live in the same area, if they live in different habitats (ex: land vs. water), then they may rarely encounter each other and thus not be able to reproduce together. Temporal isolation: If a species breeds at different times (different days, seasons, years, etc), then they will not be able to mix their gametes. Gametic isolation: Gametic isolation occurs when the one species' sperm cannot fertilize another species' eggs. This isolation can be produced in a variety of ways such as the sperm's inability to survive the reproductive tract in the other species' females and biochemical mechanisms that prevent the sperm from penetrating the other species' eggs. Hybrid breakdown and reduced hybrid fertility are examples of postzygotic barriers since they prevent a hybrid zygote from developing into a viable, fertile adult. In hybrid breakdown, the first-generation of hybrids are fertile. However, when they reproduce (either by mating with one another or with one of their parent species), the next generation's offspring are feeble and sterile. In reduced hybrid fertility, the hybrids are sterile such as that of a cross between a donkey and a horse-a mule. This can happen if the two parent species have chromosomes with different structures because meiosis will fail to produce normal gametes in the hybrids. As a result, when the hybrids mate with either of their parental species, they cannot produce offspring. Thus, genes cannot freely flow between the species as the hybrids are infertile and cannot reproduce.


what are some non examples of socialism?

Slugs and honesty are NOT social systems.


What are some examples of isolation exercises for targeting specific muscle groups?

Isolation exercises focus on working specific muscle groups. Examples include bicep curls for the biceps, tricep extensions for the triceps, leg curls for the hamstrings, and lateral raises for the shoulders.

What are some examples of cultural isolation?

Some examples of cultural isolation include communities that are cut off from the rest of society due to geographic barriers, like remote islands or secluded mountain regions. Additionally, strict religious or cultural practices that restrict interactions with outsiders can also lead to cultural isolation. Finally, certain marginalized groups, such as indigenous communities or refugees, may experience cultural isolation due to discrimination and lack of access to mainstream society.

What is a strict isolation?

Strict isolation is when a person is highly contagious and need to be kept in isolation from everyone. This is to help protect others from acquiring the virus, disease, etc. Until the Doctors determine what it may be and/or the patient recovers completely.

What species have evolved due to geographic isolation?

Some examples of species that have evolved due to geographic isolation include the Galapagos finches, Hawaiian honeycreepers, and the marsupials of Australia. Geographic isolation can lead to the development of distinct traits and adaptations in isolated populations over time, eventually creating new species.


What type of life cycle exists in which the haploid form is always unicellular as humans?

The gametic life cycle exists in which the haploid form is always unicellular as in humans.
