<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span>
Answer:
The answer is below
Explanation:
The possible phenotypes of the mother can be any of the following
AA - A phenotype
AB - AB phenotype (here the mother must have contributed an A gene for it to be possible)
AO - A phenotype (here the mother may have contributed any of the A or O gene.)
BO - B phenotype (here, the mother would only need to contribute O gene for this to be possible)
Answer:
outside the nucleus in the cytoplasm

BW 50%
WW:25%
Phenotype:
Black: 25%
Blue: 50%
White: 25%
This question is long and it is late here, but I can help you understand it. DNA consists of 4 nucleotide bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). When DNA is transferred to RNA, you use the complimentary nucleotide base to each as follows:
Adenine changes to Uracil (replaces Guanine in RNA)
Thymine changes to Adenine
Cytosine to Guanine and vice versa
So, the DNA code ‘TAC’ will have the mRNA complimentary strand of ‘AUG’. When changing mRNA to tRNA, you do as follows:
Change A to U
U to A
C to G
G to C
It’s that simple. Then, to change to amino acids, you need to use the codon chart attached (a codon is 3 nucleotide base pairs)
For example, mRNA codon AUG codes for the amino acid Methionine. Hope this helps.
