heredity Flashcards
passing of traits from parents to offspring
heredity
Experimenting with biological and chemical methods to change the arrangement of DNA that makes up a gene
genetic engeneering
the diffrent forms of a trait that make up a gene pair
Alleles
An allel on a sex chromosome
sex-linked gene
the study of how traits are inhereted through the passing of allele
Genetics
Occurs when a group of gene pairs act together to produce a trait
polygenie inheratance
A cross betweem two parents with diffrent trait ecpressions or allele thats result in the offspring looking like one of the two
hybrids
Traits that are controlled by more than 2 allele ( exemple blood types)
multiple allele
Describes a trait that is covered, up seems to disappear
Resessive
Describes a trait that covers over or DOMANTES another from of that trait
Domanant
A handy tool used to predict results in medelian genetics
punnett square
shows the genetic makeup of an orgonisum
genotype
Shows the psysical charicteristics of the way an orgonism looks and behaves as a result of the GENOTPYE
phenotype
An orgonism that has two alleles that are the same
Homosygis
An orgonism that has two allele that are diffrent
Heterosigous
Alternate form of gene are called
Alleles
The outward appearance of trait is called
phenotype
The actual combination of alleles of an orgonism it is
genotype
Humans hight, eye color, and skin color are all traits controled by
polygenitic inheratance
ALLELES seperate during
MITOSIS
control traits in organism
Genes
Treating genetic disorders by inserting normal allele into cells is called
Genetic Theripy
Occurs when a new orgonism receives more or fewer chromosomes than normal
Chromosomes disorder
Male sex chromosomesare charicterised by
