What process involves the turning off or on the genetic information of a cell

Biology
1 answer:
JulijaS [17]4 years ago
4 0

Differentiation is the process that involves the turning off or on the genetic information of a cell.

Differentiation is the process in which a young and immature cell changes into a specialized cell (a mature form with distinct function). Generic embryonic cells undergo differentiation to become specialized cells through the process of gene expression in which specific combination of genetic instructions are turned on (expressed) or off (repressed).

What is true concerning an ecological community?
Ivenika [448]

Therefore, the answer is it is a large region of multiple organisms within the boundaries

This question is unfortunately incomplete as the graph is not visible. The options given are:

B) There are probably less green parrots today than there once were.

C) Blue parrots probably are the best adapted species to live on farms.

<span><span><span> </span> </span></span>

D) The blue parrot population has likely increased in the last 200 years.


The answer is B. This is because the graph shows the highest number of green parrots in the 'deep forest' category of environment, whereas the numbers in the 'grassland' and 'scrub forest' are less. Since the forested area in Brazil has decreased rapidly, this means that the preferred environment of the green parrot has decreased, probably resulting in a decline in the green parrot population

Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses Select t
gladu [14]

Answer:

The first three steps are related to the construction of Punnett squares and the fourth step is not part of the square construction since information related to the phenotype It can be established as a conclusion or result of the genotypes obtained.

Explanation:

Punnett squares is designed to predict the mathematical probability of genotypes in the offspring, according to the genotype of the parental generation, and records only information related to this genotypes.

Taking as an example the crossing between a dominant homozygous (AA) individual for an character and a recessive one (aa), a Punnett square can be constructed:

     A. All possible combinations of alleles in the gametes produced by one parent are written along the top edge of the square :

♀️\♂<u>       A          A   </u>

    B. All possible combinations of alleles of the other parent are written along the left edge of the square.

♀️\<u>♂</u><u>       A          A   </u>

a          

a

    C. All possible genotype are written inside the boxes within the square, as they might appear in the offspring

♀️\<u>♂</u><u>       A          A   </u>

a           Aa        Aa        

a           Aa        Aa

<u>The result of the crossing of an individual with AA genotype and another aa is a offspring of Aa hybrid individuals, according to the information obtained from the Punnett square</u>.

Information related to the phenotype is not part of the Punnett square, but from the genotype a conclusion can be drawn and established, which can be written below, and not on the sides of the square. In this case, the phenotype would be 100% of individuals exhibiting the dominant character A.
