Genetics
Mutations
#
Effects
significance and effect depend on nature and position
Abnormal development
May develop other serious medical conditions like Cystic Fibrosis
May cause Sickle CDisease
Causes
Mutagen- something that causes a mutation
Ultraviolet light
Sun
Chemicals
Nitrous Acid
replaces G-C bond to G-U
Radiation
X-Rays
Gamma rays
Somatic
Mutations that do not lead to sex cells
potentially beneficial
humans
lactose tolerance
allows humans to consume milk
trichromatic vision
plants
Almonds
wild almonds can be fatal to humans
One genetic variation made them consumable
Crosses
Monohybrid
Single character is analyzed and studied
Dihybrid
Two genes are analyzed and studied
homozygous
Two dominant or Two recessive alleles
ex. RR or rr
Heterozygous
One recessive and One dominant allele
ex. Rr
Crossing over
#
Genetic variation is greater
Non-Sister chromatids exchange genes
Other Aspects or Inheritance
Maternal Inheritance
Biparental Influence
Alleles from both parents shared equally
Uniparental Influence
Genome is obtained from maternal parent "Maternal Inheritance"
Lethal Alleles
Can be difficult to detect
Presence can kill plant
Often from recessive gene and in the homozygous condition
Multiple sets of Chromosomes and gene family
Polyploid
More than 2 sets of chromosomes
Can come about by nondisjunction
gene family
multiple copies of paralogs that are similar in function
Reproduction
asexual
No genetic variation
Single copy of genes
Disease can wipe out population
Single parent
Typically associated with lower class organisms
Quicker reproduction time
sexual
Two parents
Genetic variation is greater
More readily able to fight disease
Off spring of parents have a mix of genes
Able to evolve and adapt
#
more complex organisms
Reproduction is significantly slower than asexual
