Field Of Genetics | Methods Of G Study Flashcards
To differentiate
What are the Fields of Genetics?
- Variation and Heredity
- Cytogenetics
- Molecular Genetics
- Population Genetics
- Applied Genetics
Cyto means
cell/s
describe similarities and differences among organism
variation
explain the way in which the characteristics are transmitted through successive generations
heredity
increase in the normal number of chromosomes
Trisomy
47 chromosomes instead of 46
trisomy
each cell normally contains ___ pairs of chromosomes, for a total of ___
23
46
the 23rd chromosome
sex chromosomes
What is Cytogenetics?
provide the cellular of physical basis of heredity.
provide the cellular of physical basis of heredity.

What are the methods of Genetic Study?
- Planned Experimental breeding
- Pedigree analysis
- Statistical Analysis
- Twin Study
- Karyptyping
- Microbial and Molecular Genetics
- Computer Science and Population Genetics
karyo means
denoting the nucleus of a cell.
What are the factors to be considered in choosing test organism?
- Variation
- Recombination
- Controlled Matings
- Short life cycle
- large no. of offspring
- convenience of handling
ancestral history of an individual
Pedigree analysis
A chart showing history
Pedigree analysis
predicts the probability of certain results
Statistical Analysis
provides degrees of confidence
Statcal analysis
2 types of twin study
Identical or Monozygotic twins
Fraternal or Dizygotic
Monozygotic twins means
Identical
twins developed from a single fertilized egg that splits into embryos at any early division
Identical or Monozygotic twins
twins with the same genotype
Identical
twins that result from the fertilization of separate ova and are genetically related as siblings
fraternal
twins with different genes
fraternal
Chromosome complement of a cell or an organism
Karyotype
what is karyotype??
💦complement of a cell or an organism
pictorial representation of the 💦 of an organism
karyogram
define:
karyogram
pictorial representation of the 💦 of an organism
It involves the study of the genotype of microbial species and also the expression system in phenotype
Microbial genetics
It studies th structure and function of gene at a molecular level
Molecular genetics
solutions to complex mathematical equations
Computer science and Population Genetics
