In every laboratory that uses it for experimentation, it is very important that users of the laboratory must be oriented about their safety and the code of the laboratory. For one, it will allow you to be alert at all times when using for example, an unknown chemical. Two, it will help you understand how to use the apparatus present inside the laboratory. Three it will protect you against unforeseen events. So before viewing prepared slides under a microscope, the students should review the safety rules if there are accidents such as; cutting yourself from the prepared slide, informing the professor if the prepared slide is broken, asking the laboratory-in-charge for assistance on how to use the microscope. That way, the flow of the class will run smoothly.

In humans, the "A" allele codes for Type A blood, the "B" allele codes for Type B blood, and the "o" allele codes for Type O blo

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
