Every bundle of nerve fiber is called fasciculus, it is surround by a connective tissue called Perineurium.
The expected e heterozygous phenotype would be orange.
Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).
The protein would become denatured, losing its shape, and would not be able to function properly
