The correct answer is "#2 and #3 only"
Explanation:
A and a are alleles, and R and r are alleles. Alleles of a gene are found at the same locus on homologous chromosomes. Every pair of the alleles depicts the genotype of a particular gene. Homozygous genotype occurs when two similar alleles at same locus and heterozygous in case of two nonidentical alleles. Due to the alleles there occurs a change in the appearance. An alleles create differences in gene.

Answer:
Influenza is caused by a lytic virus while Hepatitis C is caused by a non-lytic virus.
Explanation:
The lytic cycle for reproduction enables the virus to make several copies of itself and destroys the host cell in the process. Many bacteriophages (viruses that infect bacteria) adhere to the lytic cycle. During the lytic cycle, once the virus has attached itself to the host cell, it injects its DNA into it. The virus is thus able to use the host cell's machinery to synthesize proteins and replicate itself.
