Alphas ( α )

Males generally larger than omegas and alpha females

Require a daily 5,000 calories or more to keep body system functioning correctly

Have a strong, musky scent

Most have a strong guarding and protecting instinct

High levels of testosterone

React very aggressively towards other Alphas during ruts

Go into rut every 3 months; have a high need to mate

Tend to be very aggressive when mates/pups are threatened

Will spray urine to mark territory

Are traditionally seen as the breadwinners and guardians of the household

Have a knot on the end of the penis when aroused

Are very territorial and unwelcoming to other alphas

Have the alpha symbol (α) in the small of their back

Females have a functioning penis and testicles, hidden in a protective flap that resembles a vagina

Females tend to have smaller breasts

Make up 47% of the population. Of that percent, 22% are male (xy chromosome) and 25% are female (xx chromosome)

Omegas ( ω )

Tend to be smaller than alphas; omega females are generally a bit larger than males

Require a daily 4,000 calories or more to function correctly; need 6,000 when in heat, and 8,000 when pregnant

Have a sweeter, lighter scent

Although they are protective over their pups, most are possessive and tend to be hoarders

High levels of estrogen

Become closer to and seek companionship with other omegas during heat

Go into heat every 3 months; have an urge to be impregnated, but also become moody similar to a human female’s period

Will become extremely aggressive if pups are threatened

Are traditionally seen as the homemakers and child-rearers

Usually not territorial unless pups are around

Have the Omega symbol (ω) in the small of the back

Males have a functioning penis and testicles but no knot, and a birth canal leading to the anus. Females have normal female anatomy. Male omegas can impregnate female omegas.

Will nest during heat and near the end of pregnancy. Often destructive. Will hide their pups like cats and dogs, and many will dig dens or burrows to hide them in

Make up 53% of the population. Of that percent, 25% are male and 28% are female.

Both ( αω )

Have scent glands on sides of face, under the chin, thighs, lower back, and genitals

Have a high sense of eyesight, smell, and hearing

They are usually classified as heterosexual (alphaàomega or vice versa) or homosexual (alphaàalpha/omegaàomega). Heterosexuals tend to be favored over homosexuals.

Alpha/Omega are genders, male/female are sexes. Transgendered people do exist and are usually frowned upon.

Have glands on their sides that allow them to switch from human to animal form.

Oh harô, anon. I don’t know which post in specific you are talking about, since a lot of my content is tagged under “abo biology”. But I’ll just assume you’re talking about the most recent one, about claim marks given to Omegas against their will. I apologize if it’s not the one. As for your question(s). Yes a Beta CAN mark an Omega. The difference lies in that Beta claim marks tend to be weaker chemically wise. They are less packed with proteins, which is also why Beta scents are a tad more meek. On the other hand Beta claim marks tend to last longer. I like to see it as a evolutionary trait. Betas needed a way to compete with an Alpha in the case they got a fertile Beta mate or an Omega. Alpha claim marks are much stronger, which would automatically outweight the Beta’s the moment it rubbed off. But if the Beta’s body adapted and sacrificed quantity for durability, that’d make their claim marks last much longer. Giving them time to either “deafeat” the Alpha competition (if possible) while keeping their mate claimed, or move away to a safer area with a mate that is both unwilling to mate with another person other than the Beta and that will be having their scent being much less appealing to other Alphas due to the claim mark. It’s less powerful, but not necessarily less affective. And yes, Omegas can have a Beta’s babies. An Omega female will have less trouble doing it so than a male one. The probability of a pregnancy with an Alpha x Omega couple is insanely high given that they have the equivalent of fertility on steroids running through their veins 24/7; A Beta x Beta couple will have a more normal fertility rate, very similar to regular humans. Thus even if the Beta male is not engineered to be a baby-making machine, like an Alpha, the Omega female’s organism makes up for it, and their rate of fertility will be the same as a Beta x Beta couple. Omega males on the other hand will have a harder time trying to get pregnant from a Beta male. Omega males are already less fertile than Omega females, so they already carry a “liability” when it comes to that. But probability aside, there’s nothing that would “prevent” an Omega from being pregnant with a Beta male’s baby. The only thing they cannot have is an Alpha baby. See why here. 

Well, YY is not a very feasible combination by any means. The Egg of an Omega Male would promptly reject a Y sperm cell if it happened to be also a Y one, thus only open way to a X one. If by any reason the egg is unable to stop the passage of said Y cell one of two things can happen:

- A miscarriage. Seeing as the fetus would not have the correct combination it would develop in such a way that it’s not expected from the body. The Mother’s body will start perceiving the fetus as a threat or parasite and proceed to eliminate it in order to protect the mother. Thus their own immunological system acts as the catalyst for their malformed fetus’ early death.

- If the immunological system fails to promptly eliminate the fetus and he comes to be born, it will either be born dead or die shortly after. A fetus with a YY combination will not and cannot develop properly and will have a series of malformed processes that will unable it to have both the mental and physical strength to survive on it’s own.

Since the “A” allele is dominant agaisnt both “B” and “o” alleles a Beta is just as likely to have an Alpha offspring as an Omega, since the probability will be always 50%. Altought there is a popular belief that Omegas are more certain to give you Alpha pups than Betas (which is one of the many reasons that throughout History Omegas had been chosen over Betas to be courted(?) by Alphas), but mathematically speaking doesn’t change a thing. 

The difference just comes to be something tangible when it comes to the more recessive alleles. An Alpha is way more likely to make another Omega with an Omega mate than a Beta since most Alphas are offspirngs of other Alpha x Omega couples.  So there are way more Aphas with an “Ao” combination rather than “AB”. 

As for the pups, Omega Females are known to have a high rating of twins. Which is what gives them their fame of being more fertile than Betas and Omega Males (along with the fact that the percentage of risk-pregnancies in Omega females is lower than their male counterparts). The probability of both pups having different dynamics (and genders) is higher than the other way around. Fraternal twins are way more likely to happen than identical ones. Ofc they do happen, Fraternal or Identical there is still a possibility of them both being same dynamics. Fraternal possibilities - 

- May have the same dynamics and same gender. (but it’s unlikely)

- May have the same dynamics but different genders. (but it’s unlikely)

- May have different Dynamics but the same gender.

- May have different Dynamics and different genders.

Identical Possibilities - 

- Will have the same gender AND Dynamics.
