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 reproduce offspring
Asexual reproduction
cell division that results in two identical daughter cells
mitosis
cell division that produces sex cells each cell is unique (diffrent 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 a female alleles might combine in offspring
punnett square
the process by which sperm and egg combine to form an offspring
fertilization
a fertilized egg (2 haploids joined together)
zygote
a gene that is expressed only when there are two copies of the same alleles (ff)
recessive
2 copies of the same recessive alleles (small small letter gg ff)
homozygouse recessive
a gene that is expressed either with 1 or 2 copies of the alleles
dominate
2 copies of the same dominate alleles (big letter)
homozygouse dominate
a mixed gene with one dominate allele and one recessive allele
heterozygouse
father of genetics he experimented with pea plants
gregor mendal
the crossing of gene between two flowers done by insects human winds
cross pollination
