Newton's third law was that for every action there is an equal and opposite reaction.
An example might be you put your finger against a wall. There is the force of your finger on the all but also the force of the wall on your finger, the force goes both ways.
Answer:
The Genotype of a normal male wil be: XBY.
Explanation:
- A sex linked recessive disorder is expressed only in males because males have only one X chromosome and so only one allele for this gene can be present in them.
- Hence, if the recessive allele is present then colour blindness will occur.
- If the dominant allele is present then the male will be normal.
- XbY has a recessive allele so the male with this genotype will be color blind.
- XBYb cannot be aoption because Y chromosome cannot have the allele of the gene.
- XBXb is a female carrier's genotype.
- XBY has the dominant allele and so the man with this genotype will be normal.
