There are two different genotypes of brown labs and three different genotypes of yellow labs (eeBB, eeBb, and eebb) (Eebb and EEbb).
Let's examine genotypes, a different table now: As a result, a brown or yellow lab couple can have both brown labs and black or yellow labs.In actuality, neither brown nor chocolate dogs are permitted. Only yellow puppies can ever be born to a yellow lab couple. Even stranger, two brown labs can have yellow or brown puppies, whereas two black labs can have yellow or black puppies. Only yellow labs are capable of independently producing several shades of colour.

The correct option is ALL OF THESE.
Generally, three processes can lead to the removal of ions from solutions, these include;
1. The formation of an insoluble product, which is called precipitate.
2. The formation of either a non electrolyte or a weak electrolyte and
3. The formation of a gas product, which escapes from the solution.
"An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous."
