This black dog has the genotype of bb for fur color. the black dog mates and has puppies with a solid white dog. the white dog has the genotype bb. what is the probability that this match will produce puppies that are also white?

The probability of white puppies is Zero.

Genotype of the black dog is BB. This is a dominant trait, meaning that the presence of a single dominant allele ( Bb) will also give black color.

The genotype of white dog is bb. This is a recessive trait. It means that dog will express white color only if it is homozygous recessive ( bb).

When BB mates with bb, it results in all black puppies. This is so because the genotype of all puppies is Bb. Refer the Punnett square for this.

Thus, the probability that the match will produce white puppies is zero.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
