Answer:
disruptive selection
Explanation:
Disruptive selection is the natural selection that favors two extreme phenotypes but does not favor the intermediate phenotype. Here, the survival and reproductive success of two extreme phenotypes are higher than that of the intermediate phenotype due to their higher fitness value in the prevailing conditions. The presence of deeper voices in males and less deep voices in females due to high and low levels of testosterone respectively represents the disruptive selection as the phenotype present at two extreme ends are favored.

Answer:
Approximately six
Explanation:
The codon GGU
Single base substitution that will change this codon that codes for glycine to another amino acid includes: a single base substitution in the GGU codon such as GGU- AGU can occur. thus, approximately six single base substitution can take place to change this codon to code for another amino acid. A single base substitution cannot change the codon to a stop codon unless it happens twice or there is more than a single base substitution.
