That is true. Some transgenic animals grow faster because they have extra copies of growth hormone genes.
Answer:
D. organ systems
Explanation:
Organs and tissues that perform the same function are called organ systems
Answer:
Genetic relationships are analysed based on the comparison of allelic identity or differences, regardless of the number of SNPs that differ between two alleles of a gene, which simplifies the analysis.
Explanation:
Answer:
<u>Antigenic drift</u> refers to the slow accumulation of genetic changes to an influenza virus over time.
Explanation:
Antigenic drift is defined as the mechanism by which viruses undergo variation. This mechanism involves the slow accumulation of mutations in the viral genes, that are responsible for coding the antibody binding sites. This leads to the formation of a new strain of virus, which can't be inhibited by the old antibodies. Due to this, the virus can easily spread the disease.
The antigenic drift occurs in the influenza A virus and also the influenza B viruses.
Therefore, <u>Antigenic drift refers to the slow accumulation of genetic changes to an influenza virus over time.</u>
