Answer:
1
Explanation:
According to the information in this question, a gene coding for flower color in a plant is involved. The allele for red color (R) is incompletely dominant over the allele for white color (r) to form an intermediate phenotype/color i.e. Pink that is heterozygous (Rr) for the gene.
If two pink plants are crossed i.e. Rr × Rr, each parent will produce R and r gametes. Using these gametes in a punnet square (see attached image), the following offsprings will result: RR, Rr, Rr, and rr.
Out of these four offsprings;
1 RR is red : 2 Rr is pink: 1 rr is white
Hence, If four plants are produced from this cross, according to this question, the expected number of white-flowered plants will be 1 out of 4.

Hybridoma cells resulting from the fusion of B lymphocytes and myeloma cells produce specific monoclonal antibodies.
A popular technique for creating monoclonal antibodies is hybridoma technology. After immunising mice with a particular antigen, antibody-producing B lymphocytes are extracted from the animals and united with immortal myeloma cell lines to create hybrid cells, also known as hybridoma cell lines.
<h3>What is Immune system ?</h3>
A vast network of organs, white blood cells, proteins (antibodies), and chemicals make up your immune system.
- Together, these components of your body's defence system guard you against external invaders (bacteria, viruses, parasites, and fungus) that can lead to illness, disease, and infection.
- A weakened immune system can momentarily be brought on by treatments like anticancer therapies and radiation therapy, despite the fact that it is primarily brought on by certain illnesses, starvation, and specific genetic problems.
