sixth grade genetics?
No.... Like A brown coat is recessive in Labradors, while a black coat is dominant. If two hybrids are bred, what percentage will have black coats?
O.O
O.O
oh. that! ;) its easy peasy. give me one minute
Look at this chart, for example:
Ok. Let's say that the capital B [B] is the dominant allele, black coat and the lowercase b [b] is the recessive allele...are you with me so far?
yeah me too got A*. im helping her out :P
Look at this chart, for example:

The B is the dominant black coat, and the b is the recessive, brown coat.
You look at the parents of the dog [im used to doing this with human features, so i guess we'll call it 'the mum and dad of the dog'] and if they have a dominant or recessive gene, it is usually shown in the letters [B or b]. In this example, both the parents have a gene of a dominant black coat and a recessive brown coat.
On the table, you add the genes for example, B|b for mum and b|B for dad, you get Bb|bb|bB|BB. Then, in this graph, it shown 4 dominant genes and 4 recessive ones, the dominant is always overpowering so the offspring would have a black coat, but the chances are...1/2! get it?
