Answer:
it means they are only made up of one cell
For question a, Labrador retrievers vary in two loci, B and
E. Black dogs have dominant alleles at both loci (B-E-), brown dogs have bbE-,
and yellow dogs have B-ee or bbee. Since all the puppies were black, a dominant
E allele from the brown parent and they must all have inherited a dominant B
allele from the yellow parent. The yellow male must have been BBee, and the
brown female parent must have been bbEE. The black puppies were all BbEe.
For question b, simply mating yellow with yellow will produce
all yellow Labrador puppies. If at least one of the parents is homozygous EE, mating
two brown Labradors will produce either all brown puppies, or ¾ brown and ¼
yellow if both parents are heterozygous Ee.
Endocytosis is the provess used by the cell to bring in large molecules<span>.</span>
