Answer:
A and B is correct.
Explanation:
Mutations are spontaneous variations to nucleotide sequences, therefore in two animals or two chromosomes they can not be identical by nature. Therefore, the introns interact with non-coding sequences and therefore their sequences are not established as consensus in nature and are therefore highly prone to mutations.
Hence both the statement are correct.
<span>Agar
is known to be a gelatinous polymer substance that was commonly used in the
laboratory setting as a substrate. Thus, nutrients agar can grow different types
of microbes such as fungi and bacteria while MacConkey agar is made with bile
salts and crystal violets, these additives cause the agar to only grow Gram –
negative bacteria. However, nutrients agars grow more organisms because it
contains nutrients from either beef broth or yeast extracts when compared with MacConkey
agar.</span>

Answer:
The reason why the genotype and phenotype frequences do not match is just because the 1) The genotype based on genes observation,while the phenotype based on physical appearance of the organism externally
Explanation:
the genotype is looking on the arrangement of genes in pair and get its frequency ,while phenotype the external physical appearance of organism is observed to get frequency
