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-

The term that describes that individuals understand themselves as being either male or female is called <u><em>gender identity </em></u>while the understanding that maleness and femaleness are biological and cannot change is <u><em>gender constancy</em></u>.

Explanation:

Gender identity can be described as a personal perception of considering oneself as a male or female ( or both or none). It is a realization that which characteristics you possess and according to these characteristics or traits, you will fit into which sex.

Gender constancy can be described as the understanding that the biological sexes are fixed and permanent. It is a realization that changes in the gender cannot occur even if an individual changes his appearance or traits.
