Genetics Part Two
Genetics
Question | Answer |
---|---|
Genotype | genetic make-up of an organism |
Dominant | trait observed in the first generation (HH,Hh) (capital) |
Genes | one set of instructions for an inherited trait |
Blood Cells | carry oxygen & other materials through the body |
Cytokinesis | cells without a cell wall separate into two new daughter cells |
Heterozygous/Hybrid | one dominant and one recessive allele (Hh,Bb) |
DNA (deoxyribonucleic acid) | located in the nucleus of a cell, carries genetic material/ information |
Heredity | passing of traits from parent to offspring |
Interphase | longest phase, cell grows, DNA is copied, (chromosomes are copied) |
Anaphase | chromatids separate and move to opposite sides of the cell |
Mitosis | asexual reproduction, process of cell division from one parent cell |
Metaphase | nuclear membrane dissolves, paired chromatids line up at cells equator |
Chromosomes | stores genetic instructions, made up of DNA and protein, main ring of DNA |
Homozygous/Purebred | two dominant or two recessive alleles (HH,hh,BB,bb) |
Telophase | nuclear membrane forms around each set of chromosomes, chromosomes unwind |
Phenotype | physical appearance of an organism |
Recessive Trait | trait that is apparent only when two recessive alleles for the same characteristics are inherited (lowercase) (h,h) |
Prophase | chromosomes condense from long strands to rod like structures |
Order of Mitosis Phases | interphase, prophase, metaphase, anaphase, telophase, cytokinesis |
