Mendelian Genetics Flashcards
1
Q
elementen
A
Mendel
hypothesis that each parent contributes some particulate matter to the offspring
heritable substance = elementen
2
Q
Mendel’s postulates that heritable material/traits separated prior to fertilization
A
segregation
3
Q
what is independent assortment?
A
two or more traits do not always go with one another
they independently assort
4
Q
Mendel’s three laws
A
- traits are differentially expressed
- alleles dominant or recessive - principle of segregation
- two alleles for a single trait separate during gametogenesis (meiosis) - law of independent assortment
- alleles for different genes assort independently during gamete formation
- likelihood of traits appearing is a probability
5
Q
a unit of heredity
A
gene
6
Q
chromosomes
A
bundles of tightly coiled DNA that hold our genes
7
Q
alternative version of a gene
A
allele
8
Q
describes the relationship between two alleles at a locus or genetic location
A
zygosity
9
Q
if an allele is alone
A
hemizygous
