The cells divide and die at a relatively constant rate. Thus, the body permanently contains an identical number of cells. Everything is under the control of genes preventing uncontrolled proliferation.

However, they are sometimes victims of mutations and, in a certain context, the cells begin to multiply in an anarchic and uncontrolled way. It is the tumor, which can be benign (non-cancerous) or malignant (cancerous). Sometimes the body manages to get rid of it. Other times, unfortunately, this is not the case.

The cancer cell is an abnormal cell,

* which loses certain normal characters (Morphological and functional) and acquires

new specific characters that are transmitted to the child cells.

* and multiplies in an anarchic and autonomous way escaping the mechanisms of  regulation of cell division.

Cancer is characterized by a multiplication of cancer cells that divide by  mitosis. The number and the atypical character of the mitoses are in favor of the malignancy, One finds:

• Increase in the number of mitoses with shortening of the interphase.

• Abnormal, multipolar mitosis with irregular distribution of chromosomes.

It tends to expand (expansive character) in an unlimited way at the expense of the fabric in the  which it originated, but while maintaining a certain degree of differentiation related to its  original fabric.

maw [93]

The greatest number of shared derived characters should be found in two organisms that are placed in the same kingdom class.The biggest quantity of the offshore fields drives characters must be observed among the 2 organisms which are the member of the identical kingdoms magnificence area family

Shared derived tendencies derived tendencies, individual states which are shared through species and which are exceptional from the ancestral species. a collection or member this is intently associated however now no longer a member of the organization being studied.

Cladistics /Phylogeny- is a exceedingly new device of class that makes use of shared derived tendencies to set up evolutionary relationships. A derived trait is a function that advanced handiest in the organization beneathneath consideration. A phylogenetic tree primarily based totally on a cladistic evaluation is referred to as a cladogram.

Assuming no genetic recombination, how many genetically distinct types of gametes can a single human being make?
Georgia [21]

Answer:

Explanation:

Each chromosome represents a twin.like pairs of socks.

This is an analogous problem: you have 2 pairs of socks, one white, one black. Each of the sock is tailored to a specic foot, right or left. How many different ways can the socks be mixed and matched , one for each foot?

Here are the possibilities : left = black, right = black is one such match. Left = white, right = black is another.

so also we will have 23 chromosome pairs
