Suppose a male organism has a diploid chromosome number of 6. These chromosomes could be represented as A,a, B, b, C, and c wher
KatRina [158]

Answer:

A. The haploid set of n is ABC

B. ABC, ABc, AbC, aBC, abc, abC, aBc, Abc.

Explanation:

A diploid cell is a cell that comprises of two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is noted to be a homologous chromosome set. A homologous chromosome pair consists of one chromosome donated from one parent and one from the other parent. This number is represented as 2n. It varies in different organisms. A diploid cell replicates via mitosis. It preserves its diploid chromosome number by making an identical copy of its chromosomes and distributing its DNA in an equal manner between two daughter cells.

Haploid refers to a cell that contains a single set of chromosomes. Gametes are made up of half the chromosomes contained in normal diploid cells of the body, these are also known as somatic cells. Haploid gametes are produced during meiosis. Meiosis is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.

Therefore,

Karyotype of this organism is designated as AaBbCc.

AaBbCc is the diploid set (2n).

Hence ABC or abc are the haploid set (n).

B. The eight different combinations of these chromosomes that could possibly be produced by spermatogenesis in this male are:

ABC, ABc, AbC, aBC, abc, abC, aBc, Abc.

Please write a poem. Will give brainilist.
kvv77 [185]
( give it your own title )

There’s a point you need to look for in every movie, usually about half and hour before the end, when the hero is defeated in some spectacular way, beaten into submission and presumed dead. If not dead, then maybe they’ve given up, lost all hope, and there doesn’t seem to be any way to convince them to carry-on and reach for the thing they’ve been reaching for.


But then, something incredible happens. They look inside themselves and discover something that was lost - the strength to carry them on. A single spark lit a fire inside them and they return to the fight and this time they win and then the credits roll.


We tell ourselves the story again and again because it’s what we want in our darkest hour. We want to believe that something inside of us, some undiscovered or forgotten part, will help us look up from the darkness and rise to fight again.


And when in the dark, remember that this might be the part where you have to get up and fight.




ANOTHER EXAMPLE , shorter.

They love you like rain loves,
and in return, you love like a flood loves,
and just like a flood,
you are not in control
because that is the nature of your love,
and you have never learn to love
another way.

Why are some volcanoes explosive while others are not?
umka21 [38]

There are actually very few volcanoes that do not explode, but the ones that do explode with a high sound and lots of hot magma, and some are very low and don't have a lot of magma. An explosive eruption always begins with some form of blockage in the crater of a volcano that prevents the release of gases trapped in highly viscous andesitic or rhyolitic magma. The high viscosity of these forms of magma prevents the release of trapped gases.
