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

First information is gathered by any receptor. The information that gained will be processed by the brain. After that, the brain will send a signal to activate appropriate region to responses, like muscles of glands.

Answer: Each body segment of an earthworm contains four pairs of setae, which are used to move the worm. The setae of marine worms are found in bundles. Leeches do not have setae at all.
