- Punnett square
- a handy tool used to predict results in Mendelian genetics
- alleles
- different forms of a trait that a gene may have
- AB
- when a person inherits one A allele
- Mendel pea plants
- who and what helps us understand why our eye color is the way it is
- capital TT
- Mendel used this to represent homozygous for his peas
- hybrids
- plants that recieved different genetic information
- cross-polinate
- a process Mendel used pollen from flowers to purebred tall plants to pollinate by hand the flowers of purebred short plants
- multiple alleles
- a trait controlled by more than two alleles
- phenotype
- the way an organism looks or behaves as a result of its genotype
- uppercase letters
- this is what dominant stands for
- heterozygous
- an organism that has two different alleles for a trait is called
- heredity
- the passing of traits from parent to offspring
- genetics
- the study of how traits are inherited through the interactions of alleles is the science of
- purebred
- An organism that always produces the same traits generations after generations
- The father of genetics
- Mendel was known as this
- genotype
- letters that show the genetic make up of an organism
- sex-linked gene
- an allele inherited on a sex chromosome
- alleles separate
- when a pair of chromosomes separate during meiosis a trait separates into different sex cells
- incomplete dominance
- when offspring of two homozygous parents show an inheritance
- polygenic inheritance
- occurs when a group of gene pairs acts togeteher to produce a trait
- lowercase tt
- Mendel used this to represent heterozygous for his peas
- Gregor Mendel
- an Australian monk who studied mathematics and science
- dominant
- a tall form that is covered up
- homozygous
- an organism with two alleles that are the same
- recessive
- a form that disappeared
- lowercase letters
- this is what recessive stands for
- O
- recessive to both A and B blood type
- dominant alleles recessive alleles
- they ycall dominant and recessive this today
- probability
- Mendel dealt with this
- genetic engineering
- scientist are experimenting with biological and chemical methods to change the arrangement of DNA that makes up a gene
