Well I think I might know this since I was born and grew up in WI, but don't be 100% dependent with my answer because I'm only in 7th grade and I am doing high school stuff. Well my guess is the proportion of the genes is 1/2 because when a offspring is produced the genes are split from each parent rather its a human baby, a mammal, a fish, a reptile, a insect, or a plant. Although, I don't know what f1 means except for it being a control on the computer lol. But like I said I'm only in 7th grade so I don't know everything but I'm smarter than a average 7th grader.
Hope this helps! (it probably wont though)

Cell wall is not present in animal cells .
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>
