Question

complete the passage regarding inheritance of genetic conditions in humans. analyzing the pattern of inheritance for a genetic condition can help determine the mode of inheritance. if a genetic condition is not present in either parent but is sometimes inherited by their offspring, the condition is likely. if a genetic condition is not present in either parent, it is never inherited by their offspring. but when either parent is affected by the condition, their offspring have at least a 50% chance of inheriting it and the condition is likely. if a genetic condition is more readily expressed by male offspring than female offspring, the condition is likely. sex - linked + autosomal dominant + autosomal recessive +

Explanation:

1. Autosomal recessive conditions can skip generations as both parents can be carriers (not showing the condition) but pass on the recessive alleles to their offspring.
2. Autosomal dominant conditions are expressed when an individual has at least one dominant allele. If a parent has the condition (is heterozygous or homozygous dominant), there is at least a 50% chance of passing it on.
3. Sex - linked conditions often show different expression patterns between males and females due to the X - Y chromosome differences. Males have only one X chromosome, so they are more likely to express X - linked recessive conditions.

Answer:

1. autosomal recessive
2. autosomal dominant
3. sex - linked
