genetic make-up of an organism, eg., Tt
physical characteristic of an organism, eg., blonde hair
organism that has two identical alleles for a gene = pure breed=true breeding, eg., TT or tt
organism that has different alleles for a gene, eg., Tt
Heterozygous phenotype is a blend of the two homozygous phenotypes; eg., white and black result in gray
when both alleles show up in the phenotypes, eg, solid color feather parents in speckled chicken feathers
factors that determine a trait passed from one generation to the next
study of heredity; how traits are inherited from geneneration to generation
different forms of a gene
dominant allele hides or masks the recessive; represented by a capital letter
recessive allele is hidden or masked by the dominant
Law of Segregation
For sexually reproducing organisms (like plants and animals) they inherit 2 copies of each gene.
sex cells used for reproduction; guys and girls produce gametes
likelihood that a particular event will take place
the father of genetics
process in which male and female gametes join to produce a new cell
offspring between parents with different traits and characteristics..heterozygous
describes organisms that for many generations have offspring identical to the parent in a characteristic..homozygous
specific characteristic of an individual
Principle of Dominance
Some alleles are dominant and others are recessive
genes for different traits segregate independently when gametes are formed
mathematical diagram that can be used to predict the offspring of a genetic cross
more than two alleles are involved in a phenotype
involves the interaction of two or more genes
