Match each sex-linked inheritance pattern or sex determination concept on the left with its correct biological description on the right.
- Y-linked gene transmissionPassed directly from an affected father to all of his sons but none of his daughters.
- X-linked recessive carrier motherHas a 50% chance of passing the mutant allele to any offspring, making sons potentially affected and daughters potential carriers.
- Homogametic male sex determinationObserved in birds and moths where males possess two identical sex chromosomes (ZZ).
- Heterogametic female sex determinationObserved in birds and reptiles where females possess two different sex chromosomes (ZW).
Cevap
Y-linked gene transmission matches with direct father-to-son inheritance; X-linked recessive carrier mother matches with 50% allele transmission probability; Homogametic male sex determination matches with ZZ males in birds; Heterogametic female sex determination matches with ZW females in birds and reptiles.
Each genetic concept correctly aligns with its characteristic mode of chromosome transmission or gametic constitution: Y-linked traits are holandric (father-to-son), X-linked recessive carrier mothers have a 50% chance per child of passing the mutated allele, ZZ represents homogametic males in birds, and ZW represents heterogametic females in birds and reptiles.
