A parent with freckles is crossed with a parent without freckles. The Punnett square shows the possible genotypes and phenotypes of the offspring. Which statement accurately describes the probability of phenotypes?

The likelihood of the offspring having freckles and not having freckles is the same.

Explanation:

Freckles are tiny brown spots on your skin, often in areas that get sun exposure. freckles are harmless. They shape as a consequence of melanin overproduction, which is responsible for skin and hair color (pigmentation). Overall, freckles derive from ultraviolet (UV) light stimulation.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
