Bio Review 2 nd test Karyotyping vs. Pedigree Analysis- Pedigree analysis is simply the dominant trait in a family tree that continues to stand out and stay dominant. Karyotyping is the alignment of chromosomes in meiosis that is put into a picture and a gene pool is formed. Syndromes- Down- an extra copy of c’some 21… so there are 3 c’somes Turner- The woman’s version of Klinefelter, poor breast development, constriction of aorta, under developed ovaries… Klinefelter- Is a syndrome that is caused in meiosis in egg or sperm formation, lack of facial hair, and development of testes. Forms breast abnormal for any male. Nondisjunction- A fault in meiosis where the meitotic spindle does not completely separate the c’somes creates an odd amount of gametes is produced. This leads to trisomy 21 where the 3 chromosome is. Deletion vs. Duplication vs. Inversion vs. Translocation- Simply pieces of c’some taken out, replicated, rearranged, and translocation is the swapping of the parts of nonhomologous c’somes that can be cancer causing genes. Carrier- An individual that missed the inheritance of the phenotypes of a disorder, the individual received the disorder it was just recessive in the generation. Cystic Fibrosis vs. Achondroplasia vs. Huntington ’s vs. Alzheimer’s Disease-(mom) Cystic fibrosis is a disease that is carried by an individual that has both copies of the allele, and only those who have both copies of the allele will have an actual case of it. Excessive secretion of mucus is created in the lungs, pancreas and liver. (tony) Huntington’s disease is a degeneration of the nervous system and once is starts it takes 10-20 years for the effects to be fatal. Achondroplasia is a disorder where the appendages don’t fully develop but the rest of the entire body does, and it is not necessarily better to have the dominant or recessive alleles. Amniocentesis vs. Chronioc villi sampling vs. Ultrasound- All three are methods of detecting genetic disorders before birth. Chrionic villi is the most effective, its allows doctors to perform these tests earlier than the other two, chrionic villi is fetal tissue that is taken from a suction tube that is placed up the vagina. Ultrasound emits high-frequency sounds and it creates a picture so the doctors can see the anatomical deformities. Heredity vs. Genetics- Heredity is the study of generational passing of genes from the P to the F1 and F2 generations, and genetics is the study of hereditary and heredity variations. Blending vs. “Particulate” Theory (Traits are inherited like particles= genes)- Blending is a theory that red and white would make pink but it takes generations for this to happen; thus evolution. The Particulate theory….? Self-Fertilization vs. Cross-Fertilization- Fusion of male and female sex cells (gametes)
