Answer:
B. False
Explanation:
Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>
I hope you find this information useful and interesting! Good luck!

It will increase the amount of mosquitoes which will shift the ecosystem this will give many predators more to food to reproduce which will lead to a shortage of flying insects. hope this helps
Answer:
The majority of genes carried in a cell's DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.
<span>Q1. The answer is A.Biological information in a cell passes from DNAto RNA to proteins. The biological information is the part of DNA. During transcription, DNA is transcribed into RNA which now serves as a template for the synthesis of proteins. Thus, the central dogma of molecular biology describes how biological information in a cell passes from DNA to RNA to proteins.
Q2. The answer is D. 46. In a human diploid somatic cell (2n), there are 23 chromosomes present in two copies - 22 pairs of autosomes and 1 pair of sex chromosomes. So, in a normal human karyotype there will be in total 46 chromosomes (23 pairs in 2 copies: 23 × 2 = 46).
Q3. The answer is A. inbreeding. Inbreeding is a breed from closely related organisms. Inbreeding causes a decrease of genetic variation by increasing homozygosity. This way, it can cause the genetic defect by bringing two recessive alleles together.</span>
