Study of inheritance
Gregor Mendel is the “Father of Genetics”
He used pea plants because they had easily identifiable traits
Dominant- gene, trait, or allele that shows
Recessive- gene, trait, or allele that does not show
Homozygous- two of the same genes, traits, or alleles in the same individual (Double O’s)
Heterozygous- two different genes, traits, or allele in the same individual
Punnett Square- Tool used to predict two individuals offspring
Pedigree- History of an individuals traits
Carrier- heterozygous the trait is hidden
Genotype- the genetic makeup of an individual (the letters)
Phenotype- the physical characteristics of an individual (ph=ph)
A measured chance of something happening
In Genetics we are measuring the chance of individuals gaining dominant and recessive traits
Probability in a monohybrid Punnett square is 1/4 1/2 3/4 4/4
You can show this in ratios, fractions, percentages, or just numbers
Genetic representation of a family tree
Shows relationships between family members
This can be male or female, and which members are carriers for a trait
The genotype bb is ...
The genotype BB is ...
The genotype Hh is ...
the passing of genetic traits from parent to offspring.
