Genetics Flashcards
Ancestor
A person for whom one is descendant from
Descendant
A person, plant, or animal that is descendant from a 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 found in the nucleus; contains genetic information needed to carry our cells function and make more cells
Allele
One of two or more genes that may occur on a chromosome
Diverse offspring
Different combinations of allele 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 in a chromosome ; determines the inheritance of a particular trait
Heredity
the study of heredity and the variation of inherited characteristics
Sexual reproduction
genetic material is donated from two parents; offspring differ from each parent and each other (diverse)
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 two different genres for a trait (Aa)
Homozygous
If an individual carries the same two alleles for a gene (AA or aa)
Dominant Trait
inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele
