sukhopar [10]

Answer:

B) 1 black eyes, green skin, two eyes : 1 black eyes, green skin, one eye : 1 black eyes, white skin, two eyes : 1 orange eyes, green skin, two eyes : 1 orange eyes, white skin, two eyes : 1 orange eyes, white skin, one eye

Explanation:

Parentals:                     BbGgCc  x  bbggcc

The punette square diagram of the cross of these two parents is attached.

B = black eyes, b = orange eyes;

G = green skin, g = white skin;

C = two eyes, c = one eye

Progeny with BbGgCc genotype → black eyes, green skin, two eyes = 8

Progeny with BbGgcc genotype → black eyes, green skin, one eye = 8

Progeny with BbggCc genotype → black eyes, white skin, two eyes = 8

Progeny with bbGgCc genotype → orange eyes, green skin, two eyes = 8

Progeny with Bbggcc genotype → black eyes, white skin, one eye = 8

Progeny with bbGgcc genotype → orange eyes, green skin, one eye = 8

Progeny with bbggCc genotype → orange eyes, white skin, two eyes = 8

Progeny with bbggcc genotype → orange eyes, white skin, one eye = 8

So, if we will see them in the form of ratio then each of the genotype will be in the ratio of 1 i.e. black eyes, green skin, two eyes: black eyes, green skin, one eye: black eyes, white skin, two eyes: orange eyes, green skin, two eyes: black eyes, white skin, one eye: orange eyes, green skin, one eye: orange eyes, white skin, two eyes : orange eyes, white skin, one eye = 1:1:1:1:1:1:1:1.

So, in view of above option B is most appropriate.

Note: In a trihybrid cross, a total of 64 progeny types may be produced.

son4ous [18]

The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.

According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.

The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.

In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
