Assume that a polygenic character in Drosophila is produce through the activity of five genes, each with two alleles. Two indivi

777dan777 [17]

Answer:

$243$

Explanation:

Let us assume the genotype of individual with five genes is AaBbCcDdEe

If we look at the simple mono-hybrid cross between two gene pairs let us say Aa and Aa, the following genotypes will be produced

Aa * Aa

AA, Aa, Aa, aa

So total three different type of genotypes will be produced i.e AA, Aa, and aa

Like wise cross between Bb and Bb will produce BB, Bb, bb

Product of Cc and Cc will produce CC, Cc and cc

Product of Dd and Dd will produce DD, Dd, dd

Product of Ee and Ee will produce EE, Ee, ee

So in total there will be 5 such groups which will assort independently/

Thus, the probability will be

$3 * 3* 3*3 *3\\= 3^5\\= 243$

The mucous membrane that lines the eyelids and is reflected over the anterior surface of the eyeball is the conjunctiva. The muc

hichkok12 [17]

Answer:

True

Explanation:

Conjuctiva is that thin transparent mucous membrane that covers both the anterior surface and the inner surface of the eyelid. Conjuctiva is an important component of the eye that keeps the inner surface of the eyelids and the front surface of the eye moist and lubricated. It also helps protect the eye from foreign particles and from infection.

The part of the conjunctiva that covers the eyelids and is reflected over the anterior surface of the eyeball is called the bulbar conjunctiva. The part that is found coating the inner surfaces of the eyelids is called the palpebral conjunctiva.
