(27 cards)
observable traits
phenotype
name of alleles
genotype
traits that are passed from child 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
babbies
offspring
characteristics
traits
Requires male and female gametes to produce an offspring
Sexual reproduction
Does not require a male and female gametes to produce an offspring.
Asexual reproduction
cell division that results in two identical daughter cells
mitosis
cell division that produces sex cells,each cell is unique
meiosis
located in the nucleus of the cell; it is genetic material
DNA
A chance
probilaty
sex cells (egg or sperm )
gametes
Diagram showing how male and female alleles might combine a offspring
Punnett square
the process by which sperm and egg combine to form an offspring
fertilization
A fertilized egg
zygote
a gene that is expressed only when there are two copies of the same alleles
recessive
two copies of the same recessive alleles
homologous recessive
a gene that is expressed either with one or two copies of the alleles
Dominant
2 copies of the same dominant alleles
homologous dominant
a mixed gene with one dominant allele and recessive allele
heterogeneous
father of genetics he experiment will pea plants
Gregor mendel
the crossing of the gene between two flowers; done by insects ,human,winds)
cross pollination
