The answer would be no. T-Tubules or Transverse tubules are additions of the sarcolemma that infiltrate into the center of cardiac and skeletal muscle cells. There would be no functional contraction since it would not be capable to communicate or interconnect with the other cells.

When you a red bird mates with a white bird mate all the offspring have pink feathers. What can best explain this observation?
MrRa [10]

Answer:

Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance pattern in which one allele of a gene is not dominant or recessive to the other allele, hence, both alleles combine to form a third intermediate phenotype, which is a blending of both parental phenotypes.

In this case, a red bird (RR) mates with a white bird (WW) to produce offsprings that have pink feathers (RW). This shows that the allele for red coloration is incompletely dominant to the allele for white coloration, hence, both combines to produce a PINK (RW) intermediate phenotype. This portrays incomplete dominance.
