define dna
dna is located within the cell nucleus as a molecule. DNA contains hereditary material and genes, making us all unique
what is mitosis
process of cell division where a parents cell gets divided to create two new daughter cells by going through interphase, prophase, metaphase, anaphase and telophase
meiosis
cell division involving the egg and sperm cell where each daughter cell receives half dan from each parent
gene
basic unit of hereditary passed from a parent to their offspring
dominate
the dominant gene will take effect of the other allele, called recessive, is masked. and over powered
recessive
the gene that is not as strong and is not visible unless both parents have it(e.g blue eyes) recessive traits can go unnoticed and dominate traits take over
genotype
it describes an organism’s complete set of genes
phenotype
physical and observable characteristics which result from genotype and phenotype
allele
one of two or more versions of a genetic sequence at a particular region on a chromosome. An individual inherits two alleles for each gene, one from each parent
autosome
not a sex cell
sex chromsomes
type of chromosome that determines the sex of an organism
haploid
a single set of chromosomes in an organisms cell
autosomal dominant
inheritance is a way a genetic trait or condition can be passed down from parent to child
autosomal recessive
inheritance is a way a genetic trait or condition can be passed down from parent to child but recessive doesn’t usually pass down the condition from parents to offspring
x linked dominate
a way mutations can be passed to offspring in a gene on a single x chromosome
