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 recesivoIA 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 dominanteIAi, Heterocigotaii homocigota recesivo

Genotipo B:

IBIB, Homocigota dominanteIBi, Heterocigotaii homocigota recesivo

Genotipo AB:

IAIB, Homocigota dominante

Answer from: Quest

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

Answer from: Quest

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?
