Bonjour,
J'ai serieusement besoin d'aide en svt s'il vous plaît, voici la question: Un couple: l'un est albinos (homme) et l'autre non albinos (la femme) et leur premier enfant n'est pas albinos. Expliquer biologiquement ce phénomène. Préciser le génotype de l'enfant.

Merci d'avance !

Salut,

Un seul conseil : écrit les gamètes de chaque individu parent puis un échiquier de croisement et tu auras le résultats...

:)
