Genetics Flashcards
Ancestor
A person from whom one is descended from
Descendant
a person ,plant or animal that is descended from particular ancestor
asexual reproduction
genetic material is donated from only one parent; offspring are identical to the parent and each other
chromosome
made of DNA located in the nucleus; contains genetic information needed to carry out cell functions make new cells
Allele
one of two or more genes that may occur on a chromosome
diverse offspring
driftnet combinations of alleles from each parent
uniform offspring
offspring are identical to the parent
DNA
located in the nucleus; determines the genetic traits of an organism (deoxyribonucleic acid)
gene
a segment of DNA found on a chromosome; determines the inheritance of a particular trait
heredity
the passage of genetic instructions from one generation to the next
genetics
the study of heredity and the variation of inherited characteristics
sexual reproduction
genetics materials is donated from two parents; offspring differ from each parent and each other
traits
behavioral characteristics or physical attributes of an organism that are expressed by genes and/ or influenced by the environment
heterozygous
if an individual carries the different genres for a trait (Aa)
homozygous
if an induvial carries the same two alleles for a gene (AA or aa)
