The probability of their son losing his hair would depend on the specific genetic factors involved in male pattern baldness. If both parents carry the gene for baldness, then there is a higher likelihood that their son may also experience hair loss. However, baldness can be influenced by a combination of genetic and environmental factors, so it is not possible to determine an exact probability without more information.

Assumptions:
- Hair loss in males is determined by a single gene located on the X chromosome.
- Men only have one X chromosome (from their mother), while women have two X chromosomes (one from each parent).
- The gene for baldness is recessive, meaning that a person needs two copies of the baldness allele to exhibit baldness.
- The wife has a pattern of baldness, which means that she must carry at least one copy of the baldness allele.
Possible Scenarios:
1. Mother carries two copies of the baldness allele (X^bX^b):
- Man inherits the X^b allele from his mother.
- Man has genotype X^bY (bald).
- Son inherits the X^b allele from his father and the X^b allele from his mother (X^bX^b).
- Son is bald (100% probability).
2. Mother carries one copy of the baldness allele (X^BX^b):
- Man inherits the Y allele from his father and the X^b allele from his mother.
- Man has genotype X^bY (bald).
- Son has a 50% chance of inheriting the X^b allele from his father and a 50% chance of inheriting the X^B allele.
- Son has a 50% probability of being bald (if he inherits the X^b allele) and a 50% probability of having no hair loss (if he inherits the X^B allele).
Since we cannot know for sure which scenario applies, we can calculate the overall probability by considering both possibilities:
Overall Probability of Son Being Bald:
(Probability of Scenario 1) x (Probability of being bald in Scenario 1) + (Probability of Scenario 2) x (Probability of being bald in Scenario 2)
= (0.5) x (1) + (0.5) x (0.5)
= 0.75
Therefore, the probability that the son loses his hair is 75%.
