Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
- Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.
- The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.
Answer:
Homocigoto dominante, heterocigoto y homocigoto recesivo.
Explicación:
Hay tres genotipos de niños disponibles, es decir, homocigoto dominante, heterocigoto y homocigoto recesivo. En homocigoto dominante, un organismo que tiene dos alelos dominantes para un rasgo, en heterocigoto, que tiene dos alelos diferentes de un gen o genes específicos y homocigoto recesivo contiene dos alelos recesivos y expresa el fenotipo recesivo o el niño se parece al padre femenino.
No they are the same species just different breed, think of it like humans. does being light skin make you a different species? no
