The answer to this item is letter A. Stratification

The word refers to how the layers of sediments are stacked over another layer. This sediments can range from hundreds or meters to only submillimeter scale. The stratification is the most fundamental feature of the sedimentary rocks.

The small scale stratification is a result of different kinds of stratification and alternating process of deposition in the same or similar environment. There are several types of stratification: (1) cross-bedding, (2) graded bedding, (3) ripple marks, etc.

1) all the possible genotypes are also identified by color in the image below :AABBAAbB or AABbaABB or AaBBaAbB or aABb or AabB or AaBbAAbb
aAbb or AabbaaBB
aabB or aaBbaabbThere are 9 different genotypes in total. These can be achived by mixing the alleles of both genes of each parent (just like it's represented in the square).

2) there are 4 phenotypes
-one with an allele A and allele B that would dominate the other. (AABB, aAbB, for example)
- one with all alleles recessive- aabb
-one with the recessive alleles in the gene A but heterozygotic/homozigotic dominant for gene B ( for example: aaBB)
-one with the recessive alleles in the gene B but heterozygotic/homozigotic dominant for gene A ( for example: Aabb)

3) <span>probability of having offspring with the aabb genotype: 1/16
Just by looking at the punnet square, you can see that only one has the aabb genotype, in all the 16 possibilities.
