GENETICS
-Is the study of genes,hereditary,and genetic variation in living organism.
-It is generally considered a field of biology, but it intersects frequently witjh many of the life sciences and is strongly linked with the study of information systems.
GENE
-Is the basic physical and functional unit of heredity,Genes, which are made up of DNA, act as instructions to make molecules called protein.In humans,genes vary in size from a few hundred DNA bases to more than 2 million bases.
ALLELES
-Alternative forms of the same gene.
-Alleles for a trait are located at corresponding positions on homologous chromosomes.
GENOTYPE
-The genes present in the DNA or an organism.
-We will use a pair of letters (ex: Tt or Xx or ss, etc.) to represents the genotypes for one particular trait.
-There are always two letters in the genotypes because (as a result of sexualreproduction) one code for the trait.
-Comes from mama organism and the other comes from papa organism , so every offspring gets two codes (two letters).
PHENOTYPES
-How the trait physically shows-up in the organism.
TT- Homozygous=pure
Tt-Heterozygous=hybrid
ALLELES
-unique molecular forms of the same gene alternate from a gene.
DOMINANT ALLELE
-mask the expression of another allele usually a capital letter or uppercase
RECESSIVE ALLELE
-masked by the dominant allele ( small letter )
HOMOZYGOUS
-two identical alleles for a gene
HETEROZYGOUS
-two different alleles for a gene
GENOTYPE
-genetic make uo particular allele of individual carries
PHENOTYPE
-individual observable traits
MENDEL’S LAW ARE AS FOLLOWS:
-
The Law of Dominance
- one dominant trait that will mask the recessive trait.
2.The Law of Segregation
-During the transition of gametes ( sex) allele
3. Law of Independent Assortment
-alleles for different traits are distributed in sex cells to one another.

Non-Mendelian genetics: Complete and Incomplete dominance
INCOMPLETE DOMINANCE
-neither allele is completely dominant over the other allele
-heterozygous phenotype
EX.
-
4’oclock flower
Codominance
- is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
