A purple, long tailed lizard is crossed with a white, no tailed lizard. In the F1 generation all lizards are purple with a short tail. If 2 lizards in the F1 generation are allowed to breed, what would be the probability of having a short tail in the F2 generation?

Explanation:

A Purple, long tailed lizard crossed with a white, no tailed lizard.

As given,

In F1  all lizards are purple with a short tail.

PPLL ( purple, long tailed lizard)

gametes are PL, PL.

ppll( white, no tailed lizard)

gametes are pl, pl

F1  : PpLl ( purple with a short tail)

Here, it indicate that tail size follows law of  incomplete dominance

Gametes are PL, Pl, pL, pl

Cross between two F1's

PpLl× PpLl

Punnet square is:

          PL          Pl           pL         pl

PL      PPLL,    PPLl      PpLL     PpLl

Pl       PPLl      PPll        PpLl     Ppll

pL      PpLL      PpLl     ppLL     ppLl

pl       PpLl       Ppll       ppLl      ppll

So, there are 50%  short tailed. ( __Ll)
