Answer:
In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy .
In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).
Explanation:
Answer: Males inherit only one X chromosome, so they show all traits on that one chromosome without another to mask them
Explanation: Males are born with XY Females are born with XX
B.To Understand group behavior through observation
Because it’s more likely that chance events will significantly change the frequencies of alleles in the population
