4. Why was Wegener's theory of continental drift almost completely discarded? 1)It didn't explain how mountains formed.

2)It didn't explain how continents fit together.

3)It didn't have a mechanism for how drift occurred.

4)It wasn't supported by fossil evidence.

If a baby girl guinea pig looks almost identical to its mother, does this then mean that it inherited more alleles from its mother? explain. (hint: think about the vocabulary words dominant and recessive.)

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?

How many copies of genes do gametes have?
