Biochemical Genetics
36
BRANCH OF GEN -deals with behavioral traits that are inherited and how heredity and environmental influences affect behavior
Behavioral Genetics
37
BRANCH OF GEN studies genetic basis of behavioral disorders [ e.g. schizophrenia, alcoholism, manic depressive psychosis, criminality ]
Behavioral Genetics
38
BRANCH OF GEN -inheritance and expression of quantitative traits -role of genetic and environmental factors of quantitative traits -lean towards breeding
Quantitative Genetics
39
variant form of a gene or a certain trait
Allele
40
measure of how common an allele is in a population
Allele Frequency
41
are visible carrier of genes
Chromosomes
42
carries genetic material and is tightly packed into a chromosome
DNA
43
section of DNA that encodes for a certain trait
Gene
44
specific characteristics that are determined by multiple genes as well as environmental factors [ex. height, weight, IQ]
Quantitative Trait
45
a process of forming new kind of species
Species
46
describe genetics before Gregor Mendel
-heredity as “blending” process -offspring are intermediate between the parents [not true if offspring is similar to one of the parents and there are differences observed between parents and offsprings]
47
Golden Age of Greek Culture Attention was given to: (2)
Reproduction Heredity
48
main contributor in Theory of Pangenesis
Aristotle
49
Theory of Pangenesis is known as the
Greek Theory of Inheritance
50
Describe the Theory of Pangenesis
-All structures and organs of the body contribute copies of themselves to sex cells. -Semen was formed everywhere in a man’s body, reflects the characteristics of the body part from which it was formed, and traveled through the blood vessels into the male reproductive organs
51
Charles Darwin: supported Pangenesis as he discussed modes of heredity of so-called ‘_______' in his theory of evolution by natural selection
Gemmules
52
a theory based on the pangenesis theory proposed by Jean Baptiste de Lamarck
Theory of Inheritance of Acquired Characteristics
53
THEORY OF INHERITANCE OF ACQUIRED CHARACTERISTICS other term
theory of use and disuse
54
a theory stating that acquired body modifications are inherited
Theory of Inheritance of Acquired Characteristics
55
Explain the theory of Inheritance of Acquired Characteristics
-Kapag ginagamit mo nang pauulit-ulit mas mataas yung chance na ma-transmit sa susunod na generation. On the other hand, kapag naman hindi mo ginagamit; may chance na mawala -organism adapts to its environment -> modifications to the organism will arise -> such modifications are automatically handed down to its descendants = hence become hereditary
56
a theory proposed to be the fundamental mechanism of evolution
Theory of Inheritance of Acquired Characteristics
57
who developed the Germplasm Theory [also considered as the second most notable evolutionary theorist after Darwin ]
-August Weismann
58
a theory stating that germ cells are the hereditary material
Germplasm Theory
59
In Germplasm Theory, what is referred to as the is independent from all other cells of the body (somatoplasm), is the essential element of germ cells (sex cells) and is the hereditary material that is passed from generation to generation
Germ plasm
60
other term for sex cells used in Germplasm Theory
Germ cells
61
Body cells term used in Germplasm Theory
Somatoplasm
62
-ruled out the Lamarckian theory of inheritance by illustrating how germ cells but not somatic cells, function as agents of heredity.
Germplasm Theory
63
Explain the Germplasm Theory
-germ plasm, which is independent from all other cells of the body (somatoplasm), is the essential element of germ cells (sex cells) and is the hereditary material that is passed from generation to generation germplasm perpetuated themselves during reproduction generation after generation -ruled out the Lamarckian theory of inheritance by illustrating how germ cells but not somatic cells, function as agents of heredity.
64
Father of Genetics
Gregor Mendel
65
-laid the foundation for Genetics
Gregor Mendel
66
what are the hereditary factors discovered by Mendel? Referred to as now as ___________
genes
67
first to properly explains similarities & differences among parents & offspring
Gregor Mendel
68
showed that there was no blending or dilution of inheritance and provided a strong foundation of Classical or Transmission Genetics.
Gregor Mendel
69
two principles developed by Mendel
Principle of Segregation and Principle of Independent Assorment
70
two major points in the studies of mendel
1. the gene is passed on from parents to successive generations in a predictable fashion because each progeny has a physical copy of this heritable material 2. the gene codes for information that would determine structure, function, and other biological properties of the characteristic or trait that it controls.
71
-duplicated mendel's experiments on other plants
Carl Correns, Erick von Tschermak & Hugo de Vries
72
observed mendel's principles on animals
William Bateson, Saunders, & Lucien Cuenot
73
developed chromosome theory of inheritance which states that chromosomes are passed on and are responsible for passing on of genes
Walter Sutton & Theodor Boveri
74
discovered the association between specific gene and specific chromosome created the linkage map in drosophila
Thomas Hunt Morgan & Calvin Bridges
75
DNA was the hereditary material (chemical basis of heredity)
Oswald Avery, Colin MacLeod, & Maclyn McCarty
76
elucidation of DNA structure in 1953 (DNA double helix)
James Watson & Francies Crick
77
What are the application of Genetics
Microbial Plant and Animal Improvement Genetic Engineering or Recombinant DNA Technology Medicine Genetic Counselling Eugenics Euphenics Legal Application
78
there are organisms that have an abnormal count of chromosomes therefore bigger and larger in size
Polyphoid organisms
79
discovering the likelihood of inheritance of undesirable traits ; pedigree analysis of prospective parents
Genetic counselling
80
who coined Eugenics
Francis Galton
81
application of genetic knowledge for improvement of human race (looking for good traits and apply it)
Eugenics
82
medical and/or genetic intervention ; designed to reduce impact of defective genotypes on individual [ex insulin for diabetes, dietary control]
Euphenics
83
replaces Eugenics
Euphenics
84
an application of Genetics used for blood type analysis, dna fingerprinting (paternity testing, disputed parentage, criminal identification)
Legal Applications
