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.
If you are going from a high gradient to a low gradient it’s passive transport. Think of a hill if you put a rock at the top of that hill it will go down no energy involved. Active transport is going up the hill you must use energy to push that rock up the hill because it’s from a low gradient to the top. Hope this helps
