Answer:

B

Explanation:

According to Mendel, an organism receives two forms of a gene from each parent. This form received by each parent is called an ALLELE. An allele is the variant form of a gene for a particular trait.

For a diploid organism, two copies of genes (alleles) are acquired by an organism. The combination of these alleles from each parent determines the genotype for that gene.

In Mendel's experiments, he discovered that one allele can mask the expression of another for a trait. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. The combination of these alleles, whether two dominant or two recessive called HOMOZYGOUS or one dominant and one recessive called HETEROZYGOUS, determines the phenotype of the organism for that gene.

N.B: There are exceptions to this pattern of inheritance.

Why do scientists use the scientific method
Arte-miy333 [17]
The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?

Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.

Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.

If not, you reject your hypothesis.

Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
