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.
Answer:
Microbes, salts, and pollution from agriculture and industry all contribute to the problem. Global warming will likely have major impacts on the world's freshwater resources.
Explanation:
Water source protection involves the protection of surface water sources and the protection of groundwater sources from contamination of any kind. Water source protection includes basic measures and rules such as the installation of a fence around the source or the banning of grazing animals in the surrounding area.

Explanation:
Answer:
C. antigen-antibody reactions
Explanation:
human blood group is determined by the presence of antigens on the red blood cells which are specific proteins.
so specific antibodies are used against these antigens to determine the type of blood group after the reaction.
