Inheritance Patterns
recessive vs dominant
a recessive trait is one that is not pasted down as frequently as a dominant trait
a dominant trait is one that is pasted down frequently
recessive traits and dominant traits are passed down from generation to generation
Genotype and Phenotype
Genotype is the numbers/letters of the alleles
Phenotype is the description/trait
they both can have ratios within a punnett square
punnett square
can be 2 by 2
can be 4 by 4
determines the likelihood of the offspring
karyotypes
a mutation of the karyotype can cause a disorder
the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
Mendel's laws
mendel's laws are the basis for genetics
many of his laws disproved common misconceptions
nondisjunction
nondisjunction relates with karyotypes
it results in an abnormal chromosomal pattern which messes up the karyotype
An allele is one of the possible forms of a gene
Heterozygotes: an organism with two different alleles that make up their genotype
Homozygotes: an organism with the same allele that make up their genotype
