Answer:
The correct answer is - T.
Explanation:
Normally, the representation of the trait in the genotype of inheritance pattern is the first letter of the dominant character of the particular trait. In this case, the trait of the height of the pea plant is tall and dwarf.
Tall plants are dominant over the dwarf plant, therefore, the letter T would be used to represent the genotype for the height of pea plant, the small letter of the particular letter would be used to represent the alternate allele of the trait.
The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.
<h3>What is the Y-5 molar pattern?</h3>
- This is a distinctive type of molar teeth pattern found in apes and hominoids.
- In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
- Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
- A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
- In bilophodont pattern the tooth is divided into 2 symmetric sections.
- The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.
