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.

Answer:
external fertilization
Explanation:
External fertilization cannot happen on land since it needs a medium for the fertilization to be able to take place, but land cannot provide the medium.
Hope it helps.
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. ... Together, transcription and translation are known as gene expressionAnswer:
Explanation:
