The exoskeleton is the hard outer covering of the body which provides protection to the internal structure of the organism against the injury, predation, and severe weather conditions. The parts of the exoskeleton includes the nails, hooves, shells and others. The evolution of exoskeleton has supported the growth and development of the internal structures of the organisms.

1. Explain how the traits of an organism are related to the genes in DNA.
viktelen [127]

Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.

Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.

Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.

To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.
