The phenotypic ratio in this case is 9:3:3:1.
<h3>
What is phenotypic ratio?</h3>
- A phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
- The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
- A test cross is a technique used in genetics to investigate and collect potential genotypes and traits of offspring of organisms. An organism's genotype is its genetic make-up; it lists the alleles and genes that the particular organism possesses.
- The expression of genes and alleles in observable traits is referred to as the phenotype. Eye color, height, and even hair texture are examples of phenotypes.

Question:
Two pea plants are crossed. Both are heterozygous for purple blossom color, while one is homozygous for being short and the other is heterozygous for being tall. In pea plants, tall is dominant to short, and purple flowers are dominant to white. Find the phenotypic ratio.
<h2>Answer is option "B"</h2>
Explanation:
- High temperatures are not permissive for bacterial growth and lead to cellular stress, which would lead to a shift from lysogeny to the lytic phase
- Bacteriophage infection has generally been contemplated utilizing bacterial hosts developing exponentially, with dynamic air circulation, in one of a couple of all-around examined media
- The resurgence of enthusiasm for restorative, prophylactic, and agrarian phage applications, just as developing consciousness of the significant ecological effect of phages, make it progressively imperative to contemplate the subtleties of phage-have connections under conditions that are increasingly like those experienced in indigenous habitats
- Hence, the right answer is option "B"
The most common charge against health care workers is malpractice or professional negligence. This means that healthcare workers are doing something wrong, inappropriate, or out of the guidelines of the workplace.
