Ans.
A monohybrid cross can be defined as 'a cross between two individuals having different copies of a chromosome or gene of interest, which is responsible for variations in a single trait.'
These variations in a single trait are controlled by two or more alleles for a single chromosomes. For example, a cross between tall pea plant and dwarf pea plant to study the inheritance of plant height.
Thus, the correct answer is 'option). they differ in a single trait.'
Answer:
Bad mutation: deletion/addition mutation
Good mutation: silent mutation
Explanation:
Addition or deletion mutation results in the reading frame of codons to be changed, leading to a extensive missense mutation that will lead to a non-functional protein product to form.
Good mutation are silent mutations that leads to no change to the final product but causes codons to change in sequence. This increases genetic diversity in the gene pool that enables the species to be more resilient to environmental changes.
There are so many examples for that in different areas, like biology experiment carried out in our lab recently.

Answer: yes, the syprahyoid muscles are the agonist.
They are the agonists because they elevate the hyoid bone while the antagonists are the infrahyoid muscles, because they do the opposite, they depress the hyoid bone.
The infrahyoid muscles are: the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscle.
