(Hint: use a Punnett square) MacBook Air
Solution
According to the information, the genotype of parents are:
Parent 1: PPSs
Parent 2: Ppss
Thus the Punnet square becomes:
Thus the correct genotype becomes:
PPSS=0
PPSs= 4
PpSs= 4
Ppss= 4
PPss=4
It can be seen that none of the progeny will be homozygous dominant for either of the traits. However, it can be seen that all the offsprings will be occuring in a multiple of 4 thus leading to appearance of an equal number of individual for all the possible genotypes. This gives choice 2 as the correct answer.
