mihalych1998 [28]

Answer:

3/32 ttyyR-  

Explanation:

Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual

Parentals) TtYyRr      x      TtyyRr      

Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)

                 TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)

We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:

  • Shot → tt
  • Round → RR or Rr
  • Green → yy

⇒ Parent one can provide gametes tyR and tyr

⇒ Parent two can provide gametes tyR and tyr

(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =

2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =

1/32 ttyyRR + 2/32 ttyyRr =

3/32 ttyyR-

Glucose           it is a sugar and then a biomolecule. It is necessary in the

                          cellular respiration because it helps in the production of

                          ATP.

Small                90% of the absorption of the nutrients is in the Small

                          the water.
