Inheritance Flashcards
inheritance
a genetic that is passed from parent to child
genetic trait
a certain characteristic or feature of an organism that is decided by genes
simple inheritance
the inheritance of traits that are controlled by a single gene with two alleles
chromosomes
a structure that is made of DNA and proteins
DNA
the molecule that carries genetic instructions for developments and functions of an organism
Mendel
certain patterns of how traits are passed from parent to their offspring
variation
the difference between individuals of the same species
gene
a segment of DNA that codes for a specific protein
allele
one or two more versions of a gene that can occupy the same position
homozygous
an organism or cell having tow identical alleles
heterozygous
an individual or cell having two different alleles
dominant
one trait that masks the other
recessive
the masked trait that is still there but not physically visible in the offspring
phenotype
the observable characteristics or traits of an organism
co-dominant
a genetic inheritance pattern where alleles of a gene are expressed equally
incomplete dominance
a type of inheritance where neither allele for a specific trait is fully dominant
