Answer:

<u>vacuole</u>

Explanation:

Vacuoles are filled with cell sap which contains sugar, salts and waste products and enclosed by tonoplast, a membrane. They mostly act as a store for sugars and salts, they maintain the shape of the cell and play a role in osmoregulation. They are found in both plant and animal cells.

Barred feather pattern is a Z-linked dominant trait in chickens. What offspring would you expect from (a) the cross of a barred
Bezzdna [24]

Answer:

Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes Z  and W to determine sex, hens would have chromosomes ZW, and roosters would have chromosomes ZZ. A Z-linked gene is represented as a superscript on the Z chromosome, Z^{B} for the dominant allele and Z^{b} for the ressesive allele.

A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{B} & W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{b} & W \\ \ Z^{B} & Z^{B}Z^{b} & Z^{B}W \\ \ Z^{b} & Z^{b}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
