HEREDITY VOCAB

BY LILLY RYAN 2ND PERIOD

TRAIT

A CHARACTERISTIC OR PROPERTY OF AND ORGANISM

DOMINANT TRIAT

A GENETIC TRAIT PASSED FROM PARENT TO CHILD THAT IS MORE LIKELY TO BE EXPRESSED

CHROMOSOME

A TIGHTLY WOUND BUNDLE OF DNA AND PROTEINS FOUND IN THE NUCLEUS OF MOST LIVING CELLS

HEREDITY

THE PASSING OF TRAITS FROM PARENT TO OFFSPRING

GENE

THE PASSING OF TRAITS FROM PARENT TO OFFSPRING

Recessive Trait

A genetic trait that lacks the ability to manifest itself when a dominant gene is present

Allele
One member of a pair or series of genes on specific chromosomes in specific positions

Punnent Square
A chart used to determine the possible genetic outcomes for offspring of a given cross

Phenotype
The observable traits of an organism passed on from parent to offspring

Genotype
Internal genetic coding passed on from one generation to the next

HOMOZYGOUS

HAVING IDENTICAL PAIRS OF GENES FOR ANY GIVEN PAIR OF HEREDITARY CHARACTERISTICS

HETEROZYGOUS

HAVING DISSIMILAR PAIRS OF GENES FOR ANY HEREDITARY CHARACTERISTIC

DNA
Found in the nucleus of a cell, a long nucleic acid molecule containing the genetic instructions for the development and functioning of all living organisms

PROKARYOTE

INDIVIDUAL MICROSCOPIC ORGANISM WITH NO NUCLEUS

EUKARYOTE

HAVING COMPLEX CELLS IN WHICH THE GENETIC MATERIAL IS CONTAINED INSIDE A NUCLEUS
