• When gametes are formed, each allele of one parent segregates randomly into the gametes

  Law of segregation
• Sorted into gametes independently of one another

  Law of independent assortment
• Instead of one trait being dominant over the other, both traits appear.

  Co-dominance
• a blending of both alleles or when a form of a gene does not completely mask the effects of a recessive allele.

  Incomplete dominance
• Instances in which a particular gene may exist in three or more allelic forms.

  Multiple alleles
• The study of heredity.

  Genetics
• a biological process where a parent passes certain genes onto their children.

  heredity
• a molecule that encodes an organism's genetic blueprint.

  DNA
• a threadlike structure of nucleic acids and protein found in the nucleus of most living cells

  Chromosomes
• The basic physical and functional unit of heredity.

  Genes
• a cell that contains a single set of chromosomes.(ex: sperm, egg)

  Haploid
• a sex cell

  gamete
• a fixed position on a chromosome, like the position of a gene or a marker.

  Locus
• Alternative version of an specific gene

  Allele
• the particular combination of alleles for a particular gene or locus

  Genotype
• all the observable characteristics of an organism that result from the interaction of its genotype with the environment.

  Phenotype
• discovered the fundamental laws of inheritance. he deduced that genes come in pairs and are inherited as distinct units, one from each parent.

  Gregor Johann Mendel
• The creator of the Punnett square, a tool still used by biologists to predict the probability of possible genotypes of offspring.

  Reginald punnett
• What method should be used when writing the gamete combinations to solve a dihybrid cross?

  Foil method
• Use the punnett square to determine the possibility of the pea's color being either yellow or green.

  Green is dominant over yellow:

  Green - Gg

  Yellow - gg

  What is the possibility of the pea's color being green?(include percentage)

  50%

  What is the possibility of the pea's color being yellow?

  50%
• Using the Dihybrid cross, determine the ratio of the height and race of all 16 children.

  T=Tall t=short

  B=Black b=white

  TtBb x TtBb

  The probability of the children being tall and black are:

  9 : 16

  The probability of the children being tall and white are:

  3 : 16

  The probability of the children being short and black are:

  3 : 16

  The probability of the children being short and white are:

  1 : 16
