I’m not sure what your asking. But if you have 2 different alleles of a gene it will be heterozygous

The answer is the dendrites offer a big apparent area for links from other neurons. The dendrites are the main open or input areas and offer an enormous surface area for receiving signals from other neurons. They have spines appendages in which come to close interaction with synapses with other neurons.
