Without calculation what is the approximate atomic mass of neon

1 answer:

8 0

20 u

You can’t do this without some calculation.

The easiest way is to argue that most atoms of neon have <em>10 protons</em> and 1<em>0 neutrons</em>.

Each proton and neutron has a mass of about 1 u, so the approximate atomic mass of neon is 20 u.

Answer:

Genotypes: Homozygous (GG)=50%, Heterozygous (Gg)=50%.

Phenotypes: Homozygous gray (GG)=50%, Heterozygous gray (Gg)=50% or just Gray=100%

Explanation:

Hello,

The Punnett square for this cross turns into:

$\left[\begin{array}{ccc}&G&g\\G&GG&Gg\\G&GG&Gg\end{array}\right]$

It means that the genotypes and phenotypes are:

Genotypes: Homozygous (GG)=50%, Heterozygous (Gg)=50%.

Phenotypes: Homozygous gray (GG)=50%, Heterozygous gray (Gg)=50% or just Gray=100%

Best regards.
