Question

If a father has a genotype of Aa for arthritis and the mother has a genotype of aa, what is your probability that you will have arthritis?

Options:
Option 1: 100% (Certain)
Option 2: 50%
Option 3: 25%
Option 4: 0% (No probability)

Answer 1

The probability of having arthritis in this scenario is 50%.

Step-by-step explanation:

The probability of having arthritis in this scenario can be determined by understanding the principles of Mendelian inheritance.

According to Mendel's principles, when an individual with a genotype of Aa (heterozygous) for a trait is crossed with an individual with a genotype of aa (recessive homozygous), the offspring have a 50% chance of inheriting the dominant allele A and a 50% chance of inheriting the recessive allele a.

Therefore, the probability of having arthritis in this case is 50%, or Option 2: 50%.
