  1. 1. Ropali Khan Per: 3
  2. 2. <ul><li>A trait controlled by a recessive allele will only show up if the organism does not have the dominant allele. </li></ul><ul><li>In co-dominant, the alleles are neither dominant nor recessive neither allele is masked in the offspring. </li></ul><ul><li>Geneticists use punnett squares to show all the possible outcomes of genetic cross and to determine the probability of a particular outcome. </li></ul>
  3. 3. <ul><li>The Scientists started this project in 1990 and they finished in 2003. </li></ul><ul><li>The project goals were to identify all the approximate 20,000-25,000 genes in human DNA, determine the sequences of the 3 billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis, transfer related technologies to the private sector, and address the ethical, legal, and social issues (ELSI) that may arise from the project. </li></ul><ul><li>Some current and potential applications of genome research would be to diagnose, treat, and someday prevent the thousands of disorders that affect us. Learning about nonhuman organisms’ DNA sequences can lead to an understanding of their natural capabilities that can be applied toward solving challenges in health care, agriculture, energy production, and improving the environment. </li></ul><ul><li>The U.S. Equal Employment Opportunity Commission finds that people carrying abnormal genes are protected from job discrimination under the Americans with Disabilities Act. </li></ul>
  4. 4. <ul><li>Genetic disorder caused by mutation, or changes in a person’s DNA. Examples of single gene disorder is Huntington's disease. </li></ul><ul><li>A common abnormality is caused by nondisjunction, in human nondisjunction is the most often associated with the 21st chromosome, producing a disease known as Down’s syndrome (also referred to as trisomy21). Sufferers of Down's syndrome suffer mild to severe mental retardation, short stocky body type, large tongue leading to speech difficulties, cystic fibrosis, sickle cell dis </li></ul>
  5. 5. <ul><li>The genetically engineered crops are expected to </li></ul><ul><li>have a capacity to grow on lands that are presently </li></ul><ul><li>not suitable for cultivation. The manipulation of the </li></ul><ul><li>genes in crops is expected to improve their nutritional value </li></ul><ul><li>as also their rate of growth. Biotechnology, the science of </li></ul><ul><li>genetically engineering foods, can be used to impart a better </li></ul><ul><li>taste to certain foods </li></ul>
  6. 7. <ul><li>Positive genetic engineering deals with enhancing the positive traits in an individual like increasing longevity or human capacity while negative genetic engineering deals with the suppression of the negative traits in human beings like certain genetic diseases. Genetic engineering can be used to obtain a permanent cure for certain dreaded diseases. </li></ul>
  7. 8. Ocular Albinism breast tumors Albinism conjoined twins
  8. 9. <ul><li>The genes responsible for the exceptional qualities in some individuals can be discovered, these genes can be artificially introduced into genotypes of other human beings. Genetic engineering in human beings can be used to change the DNA of individuals to bring about desirable structural and functional changes in them. </li></ul>
  9. 10. The genes responsible for the exceptional qualities in some individuals can be discovered, these genes can be artificially introduced into genotypes of other human beings. Genetic engineering in human beings can be used to change the DNA of individuals to bring about desirable structural and functional changes in them.
  10. 13. Genetic engineering is the future. It can change the course of our future by improving our health. It will ultimately elongate the length of our lives and find cures for diseases that in the past had no solutions. As human beings we accept a lot changes throughout our life span, and I feel that people should be willing to accept changes that will only improve our lives.
