Answer:
Codominance

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of
Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.
The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.
As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.Learn more about X- linked traits: https://brainly.com/question/14548821

Which is a point mutation and not a frameshift mutation?
mutagen
insertion
deletion
silent
Answer:
The correct answer is D. Silent
I can assure this is the correct answer because I took either the test or review, I don't remember but yeah I know its correct also, because of the other person so be sure to say thanks to them before me!
Hope I helped! <3
A silent mutation is a point mutation and not a frameshift mutation. Therefore, the correct statement is option D.
What are point mutations?Mutagens are agents causing mutations in DNA sequence. Point mutations are due to a change in a single nucleotide base in a DNA sequence and frameshift mutations are due to changes that are the result of the insertion or deletion of nucleotide bases, thereby, shifting the reading frame of the sequence and the way is changed in which it is translated into a protein.
A silent mutation is a point mutation that does not change the amino acid sequence of a protein, as the mutated codon still codes for the same amino acid, thereby, not affecting the function of the protein.
Insertion and deletion mutations are frameshift mutations as they alter the reading frame of the sequence which results in a completely different amino acid sequence.
Therefore, the silent mutation is a point mutation.
