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.
Answer:
Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.
Cells were taken while she was being treated for cancer many years ago and these cells have been cultured in the lab ever since.
