Answer:
The percentage for the homozygous dominant trait would be 25%. in the F2 generation.
Explanation:
Suppose true-breeding parents with the different alleles for the same trait are TT (dominant) and tt (recessive) than the cross of these parents will produce gametes T, T and t, t respectively.
These gametes will form offspring ultimately. Produced offspring will be TT (homozygous dominant), Tt (heterozygous dominant), Tt (heterozygous dominant) and tt (homozygous recessive).
Thus, the percentage of dominant homozygous phenotype in F2 would be 25% in respect of the dominant allele which is TT.
A penny is at rest is experiencing inertia because it is not moving.
<h3>What is inertia?</h3>
According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.
Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.
Thus, a penny is at rest is experiencing inertia because it is not moving.
