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

Cruza: un hombre que es heterocigoto para el tipo de sangre B con una    

           mujer que es heterocigota para el tipo de sangre A

Parentales) IBi    x    IAi

Gametos)  IB    i      IA    i

Cuadro de Punnett)

                      IB          i

             IA    IAIB       IAi

               i      IBi          ii

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

Lapatulllka [165]

Answer:

Grass

Explanation:

Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses

grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

This is because it is a living thing (performs photosynthesis and cellular respiration).

Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
