The answer here would be true! hope i helped :)
Answer:
Parent 1 : AaBb
Parent 2: aaBb or Aabb
Explanation:
In this cross two genes are involved and they are duplicate genes with cumulative effect i.e. individually they show the same phenotype but when together, they produce a new phenotype. Here,
A_B_ = red
aaB_ = sandy
A_bb = sandy
aabb = white
The progeny in question has a white piglet (aabb) so it must have got a set of "ab" gametes from both parents. Since parent 1 has red phenotype it should also have one A and B allele. Hence its genotype is AaBb.
Parent 2 should also contribute an "ab" pair to white piglet and it has sandy colour which is produced by either an A allele or a B allele so its genotype should be Aabb or aaBb.
