laws of inheritance
mendel discover the basic principles of hereditary by breeding garden peas in carefully planned experiments
-
Laws of Segregation
Anaphase I or II the two alleles for a heritable character separate during gamete formation and end uo in different gametes
Metaphase I using dihybrid cross, Mendel developed
-
-
Testcross
Determine the genotype we can carry out a breeding the mystery individual with a homozygous recessive individual
Degrees of Dominance
Complete dominance: occurs when phenotype of heterozygote and dominant homozygote are identical ➜ normal mendelian genetic
Codominance: two dominant alleles affect the phenotype in separate, distinguishable ways ➜ when at least 2 alleles dominant together ➜ blood types
Incomplete dominance: the phenotype of F1 hybrids is somewhere between the phenotypes of the two parental varieties ➜ when two alleles bled together
Tay - Sachs disease
A fatal inherited disorder, a dysfunctional enzyme causes an accumulation of lipids in the brain
At the organism level, Organism level, the allele is recessive
At the biochemical level, the phenotype (that is the enzyme level) is incompletely dominant
At the molecular level, the alleles are codominant

Genetic Recombinantion
The production of offspring with combination of traits differing from either parent, completely different genes

-
Genetic Map
-
The higher the probability that a cross will occur between them and therefore the higher the recombination frequency

Syndromes
Klinefelter syndrome, is the result of an extra chromosome in a male, producing XXY individuals
Turner syndrome, produces X0 females, who are sterile; is the only known viable monosomy in humans
Cri du chat, ( cry of the cat ) results from a specific deletion
