Answer:

Gene regulation refers to the regulation of expression of a particular gene in a cell that is, it increases or decreases the expression of a particular set of genes in a particular cell.  

In multicellular organisms, gene regulation plays a crucial role in cell differentiation and maturation.  

It enables the formation of different types of cells or tissues from a single type of stem cells that is, it enables the formation of a multicellular organism from a single cell zygote.

For example, muscle cells, nerve cell, skin cell et cetera all arise from a single-celled zygote. It is possible due to highly regulated gene expression.

All cells contain the same genetic information (DNA) but different sets of genes are expressed in different specialized cells.

Which has more genetic information, a body cell or a gamete? Explain your answer
Natasha_Volkova [10]

The body cell has more genetic information. A gamete only has half the information of a body cell. So when two gametes combine (a sperm and an egg), together they provide the child with all the genetic information needed for its body cells.

Hope this helps :)

Predict the fur color of the offspring of a brown heterozygous rabbit and a white homozygous rabbit. Brown is dominant and white
fgiga [73]

Answer:

To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:

        b        b

B   Bb         Bb

b   bb         bb

The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.

there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.

The practice by which athletes abuse commercial erythropoietin by injecting it to increase the oxygen-carrying capacity of the b
Sphinxa [80]
The term Doping is essentially what athletes on Erythropoietin or EPO commonly known as use. It increases the production of red blood cells in the bone marrow. Erythropoietin is usually produced by the kidneys when oxygen in the blood gets to low levels.


The prime regulator of red cell production is erythropoietin and its major functions are to:

- Promote the development of red blood cells.

- Initiate the synthesis of hemoglobin, the molecule within red blood cells that transports oxygen.

Hope this helps you out.
