Life is found almost everywhere on Earth, but it is not distributed evenly around the planet. Different species are found in different areas; some species have overlapping ranges, others do not. Each species has a set of environmental conditions within which it can best survive and reproduce. Not surprisingly, those conditions are the ones for which it is best adapted. Many different physical, abiotic (non- living) factors influence where species live, including temperature, humidity, soil chemistry, pH, salinity and oxygen levels.
Answer:
The answer is no Human male can not be carrier for the red green color blindness.
Explanation:
Red green color blindness is a sex linked disorder that is recessive in nature. If an individual male have one copy of X gene with recessive allele of the trait he will be color blind because male have only one copy of X chromosomes and one copy of Y chromosome. So, the recessive X chromosome will express itself in absence of dominant X chromosome.
For being a carrier one should be heterozygous For this gene and its not possible in males as they have only one copy of X chromosome.
Thus, the correct answer is No.
