Heterozygous means having two different alleles.
The A allele and B allele are dominant. This means that they will be the main allele to express itself. If someone has an A and an o allele, which is recessive, the A allele would express itself over the o allele. A and B are codominant - meaning that if someone had both A and B alleles they’d have type AB blood, as they’d both express.
The mother is heterozygous type A - that means she has one A allele and one o allele
The father is heterozygous type B - meaning he has one B allele and one o allele. I know that it is Bo because if it was BA then he’d have type AB blood because the A and B alleles are codominant.
The genotype ratio is a ratio saying what the chances are of having one type of something (ex blood type, eye color) given the alleles of parents. To find this out make a punnet square with A o on top and B o on the side. Fill it in. I’ve attached a pic of what it will look like.
As you can see 1/4 is AB, 1/4 is Ao, 1/4 is Bo and 1/4 is oo. So the ratio will be letter A: AB:Ao:Bo:oo
Answer: Honestly I don't bother with such things.
Explanation: While I admit myself if i were going by the rules of the bible i would be a sinner like no other. BUt i am not a bad person, i have not done anything bad in sort, i mean i never even kissed a girl at almost adulthood now. But that bieng said I know i could never make up for all the "bad things I have done". But who says there is someone watching us? Even if there is nothing to stop us, we keep moving on like there is a "god". I belive there is too much to this topic and alot is quite unclear. I have an email if you'd like to go further in detail with things. Sorry if this wasn't what you were looking for.
Seems like Overpopulation, since they can not survive on the amount of resources available.
