Heridity

STUDY
PLAY
Heridty
is the passing of genetic material from parents ofspring.
George Mendal
was an austrailan monk. in the 1800s, Mendal performed the first major experiments in heridty.
Characteristic
is a feature that has different forms in a population.
True -Breeding
plants always produce offspring with the same trait allowed to self- pollinate naturally.
Alleles
different versions of a gene are know as alleles.
Genes
are segments of DNA. They give instructions for producing a certain characteristic.
Heterozygous
an organism with one dominant and one recessive allele fo a gene is heterozygous for that gene.
Homozygous
an organism with two of the same alleles for a gene is homozygous for that gene.
Genotype
the combination of alleles that u inherited from your parents is your parents genotype.
Phenotype
your observable traits make up ur phenotype.The phenotypes of some traits follow patterns simmilar to the ones Mendal observed.
Dominant
alleles contributes to the phenotype if one ot two copies are present in the genotype.
Recessive
allele contributes to the phenotype only whn two copies of it are present.
Complete dominance
if one chromosome in the pair contains a dominant alllele and the other contains a recessive allele, the dominant allel determines thhe phenotype is called complete dominance.
Incomplete dominance
each allele in a heterozygous individual influences the phenotype.
Co-dominance
both of the alleles in a heterozygous individual contribute to the phenotype.
