Answer:
O With training, the puppies are likely to excel at agility competitions.
O Without training, the puppies are no more likely to succeed at agility competitions than any other dog.
Explanation:
This two options speaks the same thing and are the correct option.
The phenotype of an organism is a product of genotype and environment
P=G+E
The litters can inherit the trait of running, having a good vigour and ability to win agility competition but when the environment do not allow this trait to be expressed the trait can be masked i. e may not find expression.
The environment ensure that this litters are been taught the rudiment of agility competition to ensure they win if they are not been taught, they many not know they have the ability to win and will not be different from other dogs.
The training is what brings out the potential in them that can later be seen and expressed in the competition.

This is because cyanobacteria is the oldest fossil to exist and they have been in existence for about 3. 7 billion years. These cyanobacteria photosynthesized because they have thread like chlorophyll filament, they produce food through the process of photosynthesis which is needed for their survival and they release oxygen as bye product.
<span>When a testcross between f1 dihybrid flies produces
more offspring with both traits like those of one parent, or the other than
offspring with recombinant-type traits are produced means that the two genes are
link. The reason that linked genes are inherited together is that they are
located on the same chromosome.</span>
Yes you are correct, can you put me as brainliest PLEASEEE
