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.
Yes, that is called thermal pollution
Answer:
In Prophase of Mitosis cell division, the chromatin that is present in the nucleus starts condensation.
In Metaphase of mitosis, the chromosomes arrange itself at the equator or center of the cell.
In Anaphase, the daughter chromatids separate from each other and moves towards the poles. In Telophase of mitosis, the parent cell is divided into two daughter cells.
Only one of the original DNA strands acts as a templates during replication.
