Answer:
Desmosomes
Explanation:
Desmosomes are complex structures that are disc-shaped and have the function of anchoring one cell to another. They are widely found in epithelial tissue cells, such as the spinous stratum of the epidermis.
Desmosomes have transmembrane proteins (cadherins) that guarantee the union of adjacent membranes. In addition, in plasma membrane plates facing the cytoplasmic surface, there are a number of proteins that enable intracellular anchoring, as in the case of the cytoskeleton.
Through the desmosomes, the intermediate filaments of adjacent cells connect to a “net” that spreads for several cells of the same tissue.
Answer:
1) Pp or PP → pink phenotype
2) pp → yellow phenotype
Explanation:
A dominant phenotype can be described as the physical trait which occurs due to the influence of the dominant allele. A dominant allele can be described as the allele which masks the effect of the recessive allele. The dominant allele is represented by a capital letter. Hence, the genotype showing PP or Pp will have a pink body colour as it is the dominant trait.
A recessive trait is written with a small letter, hence pp will have the recessive phenotype which is yellow.
An organism with two different genes for a specific trait is said to be “heterozygous” (b).
