"<span>Specialized cells in the epidermis produce the dark pigment known as melanin</span>" would be something that an anatomist would claim because it is something macroscopic. The rest of the options deal with concepts that happen at the cellular or molecular level (a molecular biologist would tackle them).

pochemuha

Answer:

1/2 IAIB, 1/2 IBIB (es decir, 50% IAIB  y 50% IBIB)

Explanation:

El grupo sanguíneo está determinado por un gen que posee tres diferentes variantes o formas alélicas:

alelo A: IA

alelo B: IB

alelo O: IO

Los alelos IA y IB son codominantes entre sí, es decir, un portador de ambos alelos será de grupo sanguíneo IAIB. Por otra parte, tanto el alelo IA como el alelo IB son dominantes del alelo IO recesivo. En este caso, el cruzamiento entre un individuo heterocigota IAIB con un individuo homocigota IBIB dará como resultado una descendencia 1:1 de heterocigotas IAIB y homocigotas IBIB (es decir, 50% IAIB  y 50% IBIB), ya que la madre producirá ambos tipos de gametos en proporciones equivalentes (1/2 IA  y 1/2 IB), mientras que el padre sólo producirá gametos IB.
