Explanation:
Rutherford is a chemist which performnan experiment in order to see what is present inside the atom. He bombarded radiation from a source on an atom. He observed that most of the radiation pass through the atom so he concluded that the atom has mostly empty while some comes back which means that a heavy particles are present in the nucleus.
Answer and Explanation:
<u>Cruza</u>: persona sana sin mutaciones con persona portadora
El parental sano aporta alelos normales del gen a la descendencia
El parental portador aporta un alelo normal y un alelo alterado. Tiene el 50% de probabilidad de transmitir la enfermedad a la progenie.
Parental) AA x Aa
Gametas) A A A a
Cuadro de Punnet) A A
A AA AA
a Aa Aa
F1) 2/4 = 1/2 = 50% de la progenie seran individuos sanos AA
2/4 = 1/2 = 50% de la progenie seran individuos portadores Aa
Como uno de los progenitores es portador, cada individuo tiene un 50% de posibilidades heredar el gen alterado.
