Heredity Flashcards
Observable traits.
Phenotype.
Name of the alleles.
Genotype.
Traits that are passed on from parents to offspring.
Heredity.
Segment of DNA that codes for a particular trait.
Gene.
Variety of the same gene as in dimple or not dimple.
Alleles.
Babies.
Offspring.
Characteristics.
Traits.
Requires male and female gametes to produce offspring.
Sexual Reproduction.
Does not require male and female gametes to produce offspring.
Asexual Reproduction.
Cell Division that results in two identical daughter cells.
Mitosis.
Cell division that produces sex cells, each cell is unique( different from one another).
Meiosis.
Located in the Nucleus of a cell; it is a genetic material.
DNA.
A chance.
Probability.
Sex Cells ( Egg or Sperm).
Gametes.
Diagram showing how male and female alleles might combine in offspring.
Punnet Square.
The process by which sperm and egg combine to form an offspring.
Fertilization.
A fertilized egg ( Two haploids join together).
Zygote.
A gene that is expressed only when there are two copies of a same allele (ff).
Recessive.
Two copies of the same recessive alleles (Small Small letter: gg,ff).
Homozygous Recessive.
A gene that is expressed either with one or two copies of the alleles.
Dominant.
A mixed gene with one dominant alleles and one recessive allele (Tt, Gg, Ff).
Heterozygous.
Two copies of the same dominant alleles ( Big Big letter: TT,GG,FF).
Homozygous Dominant.
Father of genetics. He experimented with pea plants.
Gregor Mendel.
The crossing of gene between two flowers; done by insects, human, winds.
Cross Pollination.
The crossing of genes between two animals of the same species; human involve involve in the breeding to select desired traits.
Cross Breeding.
A pure homozygous Dominant or homozygous Recessive.
Purebred.
A mixture of two gene one Dominant and one Recessive.
Hybrid(mutt).
