Unit 9 Inheritance Patterns
Monohybrid
4 squares
mother and father genotypes
one trait (gene)
Dihybrid
16 squares
mother and father genotypes
two traits (gene)
Karyotype
displays number visual appearance of chromosomes in a human
Chromosome 1 largest and gets smaller
23 pairs of chromosomes (46 total)
Genetic Mutations
paracentric vs pericentric
fission vs fusion
duplication vs deletion
translocation (reciprocal)
Pedigree
shaded = affected person
records traits passed down by generations
square: male, circle: female
Dominant vs. Recessive
dominant and recessive alleles in genes
recessive: must be recessive homozygous to show recessive trait
dominant: more common and heterozygote has dominant trait
Turner's Syndrome
female born with only 1 X chromosome
45, X, -23
delayed puberty, infertility
Klinefelter's Syndrome
male born with extra X chromosome
47, XXY, +23
little testosterone and reduced muscle mass
Down Syndrome
47, XX or XY, +21
extra chromosome in Chromosome 21
mental disabilities and distinct physical appearance
Mendel's Laws
Law of Dominance
Law of Segregation
Law of Independent Assortment
