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).

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.

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>
A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
Answer:
Increases
Explanation:
The movement of particles of the matter increases with the increase in temperature.
The particles gain kinetic energy with increasing temperature and move in faster rate.
<u>For example:</u> When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.
Hence, the correct answer is "increases".
Answer:
I think farm expenditures
The hypothesis is the question you are trying to answer or the problem you need to figure out, it is kind of like a starting point
