Answer:

F1) 1/4 = 25% de la porgenie será AB, IAIB

1/4 = 25% de la progenie será heterocigota para el tipo A, IAi

1/4 = 25% de la progenie será heterocigota para el gruo B, IBi

1/4 = 25% de la progenie será homocigota recesiva, ii

Explanation:

El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I.
En personas de tipo A, los alelos son IA dominante, i recesivo.
En personas de tipo B, los alelos son IB dominante, i recesivo
IA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.
El alelo i es recesivo siempre.

Genotipo A:

IAIA, Homocigota dominante
IAi, Heterocigota
ii homocigota recesivo

Genotipo B:

IBIB, Homocigota dominante
IBi, Heterocigota
ii homocigota recesivo

Genotipo AB:

IAIB, Homocigota dominante

How does extinction affect evolution?

Semenov [28]

If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.

Endospores are resistent structures that contain cytoplasm and genetic material, and can ____________ when favorable conditions

QveST [7]

The blank space in the task content should be filled with; develop into new organisms.

<h3>What are endospores?</h3>

Endospores as their name implies are formed within the cells of bacteria as an alternative reproduction mode. The spores in discuss are formed within bacteria vegetative cells or mother cells known as sporangia. The endospores therefore are able to develop into new organisms provided that the conditions become favourable.
