Multiple Choice

Question image
 Look at the Punnett square. If the two parents represented in the Punnett square have four offspring, what does the Punnett square tells you?
1
two of the offspring will definitely be heterozygous.  
2
one of the offspring will definitely show the recessive trait.
3
there is a 50% chance for each of the 4 offspring to have the genotype Rr.
4
there is a greater chance for the offspring to be RR than rr.
