Notes 14.1
• Karyotype
– Shows the complete diploid set of
chromosomes grouped together in pairs in
decreasing size.
• Genome – full set of genetic
information
Sex Chromosome – 2 of the 46
Chromosomes determine sex
Autosome – the other
44 chromosomes
• Many human traits follow a pattern of
simple dominance – Ff, FF, ff
• Sex Chromosomes – determine an
individual’s sex. Females have 2 XX’s
Males an X and a Y.
• Female – XX
Male – XY
• A sex-linked gene is a gene located on a
sex chromosome.
• The information gained from pedigree
analysis makes it possible to determine
the nature of genes and alleles associated
with inherited human traits.

Notes 14.2
Small changes in DNA molecules can affect
human traits.
Individual Gene Disorders
•
Base change from Guanine to Adenine
produced dry ear wax instead of wet earwax.
(Substitution)
•
Deletion of 3 bases in a gene causes cystic
fibrosis. (deletion)
•
The codon CAG replicats over and over more
than 40 times creates Huntington’s Disease
(Duplication)
Genetic Advantages – Some diseases make humans
immune to other infections even if they are just a
carrier.
• Those with sickle cell anemia are immune to
Malaria.
• Those with Cystic Fibrosis are immune to typhoid
fever.
Chromosomal Disorders
nondisjunction – (not coming apart)
chromosomes fail to separate creating three
copies – trisomy
• Down Syndrome
Nondisjunction of the X and Y chromosome
• Turner’s syndrome – Females
• Klinefelter’s Syndrome – Males
THURSDAY

Objective: I will understand the purpose of
selective breeding through discussion and
review.
Notes15.1
Selective Breeding – allowing only desired
characteristics to produce in the next
generation.
Hybridization – crossing dissimilar
individuals to bring together the best of both
organisms.
•often hardier than either parent
Inbreeding – continued breeding of
individuals with similar characteristics.
•pedigree dogs
Increase genetic variation by introducing
mutations.
Biotechnology – when scientists manipulate
the genetic makeup of organisms through
technological processes, inventions, or
method.
• Bacterial Mutations – using radiation or
chemicals
• Polyploidy – drugs that increase the
number of chromosomes – producing
larger stronger plants.
