enyata [817]

Answer:

At dawn the squid prepares to hide in the sand for the day and it ejects about 95% of the bacteria from the light organ in order to reduce or stop the growth of bacteria population in the squid. This will prevent the bacteria population from reaching a level too high for the squid to support.

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.
