Blood typing is a method to tell what type of blood you have. Blood typing is done so you can safely donate your blood or receive a blood transfusion. It is also done to see if you have a substance called Rh factor on the surface of your red blood cells.

Arlecino [84]

<h2>Answer is option "C"</h2>

Explanation:

All in all, this procedure includes a "parent" cell parting into at least two "little girl" cells. Right now, parent cell can give its hereditary material from age to age.
Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.
In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
Hence, the right answer is option C "four strings, each a combination of different colors"

Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t

Gelneren [198K]

Answer:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

A (colored seed) is dominant over a (colorless)
Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A Aa WxWx individual was test crossed (crossed with a homozygous recessive aa wxwx individual).

The homozygous recessive can only produce a wx gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 A Wx and 1/2 a Wx

The possible offspring resulting from the combination of those gametes is:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).
