Answer:

Please see the answer below

Explanation:

a. The roman numerals represent the various generations in the pedigree.

    I represents first generation

   II represents the second generation

b. The half shaded square and circle representing the parents means that both of them are carriers for the trait in question. <u>Tay-Sachs disease is an autosomal recessive inheritance, assuming the trait is represented by the allele </u><u>a</u><u>, the gentoypes of the parents would be </u><u>Aa </u><u>and </u><u>Aa </u><u>respectively.</u>

c. Still on the assumption that the disease is represented by the allele a. If offpsring II4 which happens to be free of the Tay-Sachs allele marries a person that also does not carry the Tay-Sachs disease gene, the cross will be as shown below.

AA   x   AA = AA, AA, AA, and AA.

<em>All the children would be free from the Tay-Sach's allele. That is, they will be homozygous normal.</em>

How does the shape of vomerine teeth help it preform its function?(holding prey) This question is about frogs in case there is a
Umnica [9.8K]

Answer:

The <u>shape in V</u> of the vomerine teeth is useful to <u>hook the prey and hold i</u>t until the frog can swallow it.  

Explanation:  

In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.

Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.

Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.

These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.

The<u> shape in V</u> of the vomerine teeth is useful <u>to hook the prey and hold it </u>until the frog can swallow it.
