Observer each image of the punnet square and list the two phenotypes and the probability of each phenotype occurring.
Marta_Voda [28]

Answer:

In the crossing of two hybrid plants for the color flowers trait can be seen that the phenotypes are purple flowers and white flowers and in the descendants the phenotypes, genotypes and probabilities are purple flowers Bb (50%), purple flowers BB (25%) and white flowers bb (25%).

Explanation:

For the flower color trait, the dominant allele is purple (B) and the recessive allele is white (b). The planted cross shows two purple hybrid flowering plants (Bb) and the offspring can be seen in Punnet square:

<u>Crossing: Bb X Bb </u>

Alleles    B     b

B            BB   Bb

b            Bb   bb

The results in the offspring are:

  • <em>Plants with purple heterozygous flowers Bb 50%. </em>
  • <em>Plants with pure purple flowers BB 50%. </em>
  • <em>Plants with white flowers bb 25%.</em>

In the direct case, the  chemo receptors,  found in the carotid body located at the carotid artery  monitors and detects  levels of pH in the cerebrospinal fluid, oxygen and carbon dioxide in the blood and helps in breathing, the rate and depth of  of breathing according to a person's needs that is why it is very difficult for one to suffocate by holding their breath because these nerve  cells will  trigger back to the respiratory centers, an involuntary breathing response due to the critical signals  of chemicals they detect in the blood.

Indirect chemo receptors can be found in the nose and tongue for detecting smell and taste.
