Science Final Flashcards
A physical characteristics that is passed from parents to their babies, or offspring
Inherited traits
The passing of genetic traits from parents to offspring
Heredity
He is born in Czech Republic
Gregor Mendel
What year does Gregor Mendel born
1822
What is the full name of Gregor Mendel
Gregor Johann mendel
He studied the inheritance of traits in pea plants
Gregor mendel
He is the father of genetics
Gregor Mendel
Why Mendel chose pea plants for his experiment
- The flowers for pea plant are bisexual
Why Gregor Mendel chose pea plants for his experiment
- They are self pollinating, thus, self and cross pollination can easily be performed
Why Gregor Mendel chose pea plants for his experiment
- The different physical characteristics were easy to recognize and study
Why Gregor Mendel chose pea plants for his experiment
- Pea plants have short life span and are easier to maintain
Each trait is controlled by 2 factors
Law of dominance
What is expressed
Dominant
Masked in presence of dominant
Recessive
Each allele separates into different gametes
Law of segregation
Gene pairs (homologous) will separate randomly into gametes during meiosis
Law of independent assortment
A heritable factor that controls a specific characteristic
Gene
Alternative forms of gene
Allele
The trait we see (expressed with capital letter A)
Dominant
Trait that is masked (expressed with lower case letter, a)
Recessive
The genetic makeup of a cell, an organism, or an individual that contributes to it’s phenotype
Genotype
Are the observable and measurable characteristic of an organism
Phenotype
P1 or P
Parents
F1
1st filial generation offspring
