Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.

Abiotic factors composed of water, light, temperature and air etc. due to fire's this primary succession was completely destroyed. Their remaining organic bodies were decomposed in soil texture.
In order to establish secondary succession there is need of water and light, because water help in translocation of food and nutrients in plants while light is important for photosynthesis.
Photosynthesis need three major components. these are H₂O, CO₂ and light, all these components are abiotic part of ecosystem. However, when secondary succession occurs, then light play a key role in changing the composition of plant community. The best example is the difference in height of plants of different community.
Answer:
Fossil Evidence and Structural evidence proves to support the theory of evolution because fossil evidence shows how animals looked like a few hundreds to thousands of years ago, and structural evidence shows how an animal can change from a land creature to a sea creator such as a whale starting from Indohyus to becoming a whale as it is now.
