How does mutation, random fertilization, and crossing over contribute to genetic variation?

Biology
1 answer:
yaroslaw [1]3 years ago

Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !

random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !

and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !

kvv77 [185]

Answer:

Coagulative necrosis

Explanation:

  • When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
  • During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
  • When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
  • All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .
