- Allele
- *"options " for a gene/trait
- Anaphase
- *chromatids move away, nuclear membrane is absent, and the chromsomes move away from each other
- Autosomes
- *Normal Chromosomes
- Centromere
- *the part of the chromosomes that connects the two parts together
- Chromosomes
- *Long strands of DNA
- Coarse Adjustment
- *were u adjust the stage
- Crossing Over
- *Pieces of homologous chromosomes trade places , process of the chromosomes switching places
- Diploid
- *cells with 2 of every chromosomes
- Dominant
- * Allele that will always show if present(capital letter)
- Gametes
- *egg or sperm
- Heterozygous
- * different 2 alleles in genotype*also called a hybird
- Homozygous
- *same 2 alleles in genotype *also called a purebread
- Karyotype
-
*picture of chromosomes,
can tell you if the baby is a boy or girl, or if there is any added or extra chromosomes - Interphase
- *normal phase, nuclear memberane is present, chromsome is not visible
- Sex Chromosomes
- *chromosome that determines gender
- Phenotype
- *the physical apperance from the genes
- Prophase
- *chromosomes are visible , nuclear memebrane is breaking a part
- Recessive
- *allele that will be hidden by a dominant allele (lower case letter)
- Genotype
- *Combination of alleles for a gene.
- Telophase
- *two new cells, necular membrane has reformed , and the chrosomes begin to disappear
