incomplete dominance
law of segregation
sex - linked inheritance
codominance
a person with type ab blood shows both a and b types at the same time. both are fully expressed
sex - linked inheritance
fragile x syndrome is a genetic disorder carried on the x chromosome. males are more likely to have it than females
law of segregation
a red flower is crossed with a white flower, and the offspring is pink
incomplete dominance
a parent with bb (brown and blue eye alleles) passes on either b or b, not both. each offspring receives one from each parent

Explanation:

Match each genetic concept to its defining example based on core inheritance traits:

1. Codominance occurs when both alleles are fully expressed simultaneously.
2. Sex-linked inheritance involves genes on sex chromosomes, affecting males more often.
3. Law of Segregation states alleles separate, only one passed to offspring.
4. Incomplete dominance results in a blended phenotype of parents.

Answer:

• Codominance → a person with type AB blood shows both A and B types at the same time. Both are fully expressed
• Sex-linked inheritance → fragile X syndrome is a genetic disorder carried on the X chromosome. Males are more likely to have it because they only have one X chromosome
• Law of Segregation → a parent with Bb (brown and blue eye alleles) passes on either B or b, not both. Each child receives one allele from each parent
• Incomplete dominance → a red flower is crossed with a white flower, and the offspring is pink
