If a tt plant is crossed with a tt plant, what is the chance that a tt offspring will be produced? 75% 25% 50% 100%

the correct answer is 25%

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

% of Offsprings with tt genotype =

                                                      =  25%

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom
