Question

1. If tall is the dominant trait (T), the genotype for a person who is short would be

a ss

b. TT

c tt

d Tt

Answer 1

a: ss

If T is dominant, every genotype which contains a T or contains two recessive t types, will result in a tall person. Therefor, only ss is the correct answer.

Good luck with your Bio ;-)

Answer 2

c

Answer 3

well T is used to denote tall trait and t is used to denote short trait..since T is dominant so in option Tt it wud not let t express itself so option d is wrong coz the individual is gonna be tall...in option TT both the allels are dominant ones representing tall trait so the individual will be tall..this option is also wrong and as  for ss ..u have specified that tall trait is represented by T so the short is represented by T, so option c is correct coz both the alles are recessive so the individual will be short.....

Answer 4

obviously its tt thats (c).

bcoz dwarfness is a recessive trait. in Tt tallness will dominate dwarfness

Answer 5

tt

Answer 6

C. tt

Lowercase letters are usually representative of recessive genes. Thus, a person with TT=tall, Tt= tall (dominant masks recessive), and tt= short. In this case, ss is not representative of any trait.

Answer 7

I believe it's c: tt; you need to have the recessive trait twice to make it visible, or else it's just genetic code.

- ss doesn't stand for anything there, as you use the same letter for the dominant and the recessive trait (T and t; S and s; etc)

- TT would be the genotype of a tall person, obviously; and so would Tt, because even though there is a t, the T, being dominant, represents the trait the person actually shows.

Answer 8

tt. Dominant trait can always be TT or Tt. recessive trait will be lowercase letters ONLY tt
