White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with a homozygous recessive canary.
Lera25 [3.4K]

<em>2:4 homozygous recessive; 50% heterozygous.</em>

Explanation:

I will be using the letter B to represent dominant alleles and b to represent recessive alleles.

If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).

If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).

I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...

<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.

<u>50%</u> of the offspring will be <u>heterozygous</u>.

The photosystems and electron transport chain components are embedded in the thylakoid membrane.

Marta_Voda [28]

Answer:

The correct answer is option a. "hematopoietic (blood) cells, or the cells that give rise to mature blood cells".

Explanation:

Leukemias and lymphomas are two forms of blood cancer. The difference between leukemias and lymphomas, is that leukemia affects the blood and bone marrow, and lymphoma affects only the lymph nodes. Wherever the location affected by these two diseases, Leukemias and lymphomas arise from the transformation of hematopoietic (blood) cells (or the cells that give rise to mature blood cells) into hematologic malignancies.
