<h2>The correct answer is: Deflation.</h2>

Explanation:

  • In geology, Deflation can be defined as the process by which loose, light weight and small particles formed by the weathering of rocks, erosion of top-soil of the earth crust or the dust and sand particles are carried from one place to another by the action of wind.
  • When these particles hit or strike an obstruction like a mountain or hill they fall down on the ground.
  • Gradually with time, numerous such particles fall down and accumulate on the ground after striking an obstruction and eventually result in the formation of a sand dune.

In Africa, dragon color is co-dominant. The colors blue and yellow are co-dominant.
pshichka [43]

1 Blue and yellow: 1 yellow

Let us assign the allele for Blue dragon color as B and that of Yellow dragon color as Y and create the punnet square below;

The phenotypic ratio will, therefore, be;

1 Yellow/Blue : 1 Yellow

The syntenic genes A and Z are linked. A cross between two parents, AAZZ and aazz, produces F1 progeny with the AaZz genotype. W
garik1379 [7]

Answer:

The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Explanation:

The genotype of F1 progeny  is AaZz

The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"

Thus, total four allele pairs will be formed.

First allele pair would be - AZ

Second allele pair would be - Az

Third allele pair would be - aZ

Fourth allele pair would be - az

Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
