Match the following terms and definitions. 1.breeding of individuals that have genes for two different characteristics codominan
Luden [163]
<span>Answers;
1.Breeding of individuals that have genes for two different characteristics; Dihybrid cross
2.A grid system used to predict possible combinations of genes due to random fertilization; Punnet square
3 A condition in which both alleles are dominant; Codominance
4.when more than two alternatives exist for a gene; multiple alleles
5.A condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype ;Incomplete dominance;

Explanation;
</span>Dihybrid cross;
<span>It involves the breeding of individuals that have genes for two different characteristics. It involves the cross of individuals that are both heterozygous for two different traits. For example two different traits in a pea plant; color and shape; for color we have; Y-allele for yellow seeds and y- allele for green seeds, For Shape trait; R-allele for round seeds and r-allele for wrinkled seeds. So the dihydbrid cross would be (RrYy </span>× RrYy). 
<span>
Punnet square;

</span><span>This a grid system or a square diagram that is used to predict possible combinations of genes due to random fertilization. It is used by biologists determine the probability of an offspring having a particular genotype. 
</span><span>The letters on the outside of a Punnett Square stand for the parent allele.
</span>
Codominance
;
<span>This is a condition in heterozygotes in which both members of an allelic pair are dominant and both contribute to the phenotype. 
A good example of codominance is the ABO blood group; A person with blood group AB, it means that both the A allele and B allele are equally expressed. 

Multiple alleles

</span><span>This is when more than two alternatives for a gene exist.
Examples of multiple allelism in human;The genes of the ABO blood group system. The human ABO system is controled by three alleles, namely; A-allele, B-allele and O-allele.

Incomplete dominance;
</span><span>This is condition in heterozygotes in which both members of an allelic pair are neither dominant nor recessive to other alleles, so the two traits blend in the phenotype of the individual. 
An example; is a snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower. Which means neither the white allele or the red allele are dominant. </span>

Answer:

isotonic: two solutions having the same osmotic pressure across a semipermeable membrane

hypertonic: shrink. solution is one in which the concentration of solutes is greater inside the cell than outside of it

hypotonic: swell. solution is one where the concentration of solutes is greater outside the cell than inside it

What powers did The Empire of Great Britain have over its people<br>​
zhuklara [117]

Answer:

The Empire of Great Britain had a "global power," which was also known as a "superpower" concerning resources, influences and geopolitical landscapes.

Explanation:

<em>When it comes to international relations, the power of a country or a nation is very important.</em> It is an inherent goal that many people want. It can be used in many situations such as<em> cooperating with other countries, coercing people to follow a rule, securing the nation and developing the nation, etc.</em>

The Empire of Great Britain was considered, together with USA and the Soviet Union, to have a "superpower." Only the strongest nation possess such power. It was able to control millions of people, which then resulted into a great expansion. <em>The reason behind this is that they had a stricter rule than other nations and people followed it.</em> This made them stronger and while they continued expanding, they were able to acquire more resources.
