Genetics Flashcards
Ancestor
A person from whom one is descended from.
Descendant
A person, plant, or animal that is descended 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 located in the nucleus; contains genetic information needed to carry our cell functions and make new cells.
Allele
One of two or more genes that may occur on a chromosome.
Diverse offspring
different 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
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 environments.
Heterozygous
if an individual carries two different genes for a trait.
Dominant trait
inherited characteristics that appears in an offspring if it is contributed from a parent through a dominant allele.
