Question

correct answer(s)
autosomal recessive
sex - linked
autosomal dominant
incorrect answer(s)

Explanation:

Since the problem involves analyzing a pedigree chart to determine the mode of inheritance (which is a key aspect of genetics in Biology), and the options given are related to genetic inheritance patterns (autosomal recessive, sex - linked, autosomal dominant). In a sex - linked (specifically X - linked recessive) inheritance, males (who have one X chromosome) are more likely to be affected. In the given pedigree, two males (in generation III) are affected. Autosomal recessive would require both parents to be carriers (if they are normal) to have affected offspring. Autosomal dominant would likely show a more continuous pattern of affected individuals in each generation.

Answer:

sex - linked
