Punnet Square
used to calculate and depict all the combinations of the different genotypes and phenotypes among the offspring
Phenotype-
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
Genotype
the genetic constitution of an individual organism.
Recessive Trait
inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele
Homozygous
If an individual carries the same two alleles for a gene (AA or aa)
Heterozygous
If an individual carries two different genres for a trait (Aa)
Traits
behavioral characteristics or physical attributes of an organism that are expressed by genes and/or influenced by the environment
Sexual reproduction
genetic material is donated from two parents; offspring differ from each parent and each other (diverse)
Genetics
the study of heredity and the variation of inherited characteristics
Heredity
the passage of genetic instructions from one generation to the next
Gene
a segment of DNA found on a chromosome; determines the inheritance of a particular trait
DNA
located in the nucleus; determines the genetic traits of an organism (deoxyribonucleic acid)
Uniform Offspring
offspring are identical to the parent
Diverse Offspring
different combinations of alleles from each parent
Allele
one of two or more genes that may occur on a chromosome
