If an organism is homozygous for a particular trait, the organism A. has extra alleles on both chromosomes in a chromosome pair. B. has the same allele on both chromosomes in a chromosome pair. C. is missing alleles on the chromosomes in a chromosome pair. D. has different alleles on the chromosomes in a chromosome pair.

B. Has the same allele on both chromosomes in a chromosome pair.

Here is why:

Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.

There can be two types of homozygous alleles.

~

Homozygous Dominant: BB

Homozygous Recessive: bb

Notice in both of these they were the same alleles.

~

Heterozygous: Bb

Notice how both are different alleles.

Below I have attached a diagram of a Punnett square I have made.

On the left is a homozygous recessive allele pair.

On the top is a heterozygous allele pair.

hi, natural selection of the peppered moth during the industrial revolution in 19th-century england is an example of an outlier in the study of evolution. during this time, pollution from factories filled the forests, coating trees in a layer of soot—turning white trees black

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
