When are the genetic traits of parents transmitted to the offspring?

Study the following cross showing self-pollination in $F_1$ generation,fill in the blank,and answer the question that follows:
Parents: $RRYY \times rryy$
(Round,yellow) (Wrinkled,green)
$F_1$: $RrYy \times$ ?
(Round,yellow)

What is the scientific name of the human species?

Does geographical isolation of individuals of a species lead to formation of a new species? Provide a suitable explanation.

In the following crosses,write the characteristics of the progeny:

Cross	Progeny
$(a)$ $RR YY \times RR YY$ (Round,yellow $\times$ Round,yellow)	..........
$(b)$ $Rr Yy \times Rr Yy$ (Round,yellow $\times$ Round,yellow)	..........
$(c)$ $rr yy \times rr yy$ (Wrinkled,green $\times$ Wrinkled,green)	..........
$(d)$ $RR YY \times rr yy$ (Round,yellow $\times$ Wrinkled,green)	..........
