Answer;

D) D

(Gap junctions)

Explanation;

Gap junctions are tunnel like junctions that can occur anywhere along the lateral membranes of adjacent cells. They  allow ions and small molecules to pass to one cell to the next for inter-cellular communication.

They function by allowing the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.The protein channels that make up gap junctions consist of two connexons. One connexon resides in the membrane of one cell.

Answer:

The correct answer is - 30.25%

Explanation:

Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.

The population has the allele frequency or q = 0 .55

So, the percentage of the white spots moth in this moth population would be -

q^2 = (0.55)^2

q^2 = 0.3025

q^2 = 0.0325 *100

= 30.25 %

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.
