Question | Answer |
what is an allele? | ways to express a gene |
what is a genotype? | the genetic make up of a trait |
what is a phenotype? | the outward physical appearance of a trait |
Sex cells, or gametes are formed during? | meiosis |
somatic cells or body cells are formed during? | mitosis |
Mitosis and meiosis are the same because? | they both contain genetic information, they both copy chromosomes, they both split into new cells |
Mitosis and meiosis are different because? | mitosis is an exact copy maintaining chromosome numbers Meiosis is a hapliod or half of the genetic information from parent cell |
What is genetics? Heredity? | Study of traits passed from generation to generation. Heredity- passing of traits from parent to offspring |
Who is the father of genetics? | Mendel |
What is crossing over and what does it accomplish? | when homologous chromosomes exchange each others genetic code. It accomplishes variety in the system |
Males have which sex chromosomes? Females? | XY, XX |
AA is an example of ? | homozygous dominanat |
Aa is an example of ? | heterozygous |
aa is an example of ? | homozygous recessive |
Why are sex linked traits more common on the X chromosome? | every one has one |
Law of independent assortment means? | genes separate during gamete formation without influencing each others inheritance |
what is a karyotype? What can it show? | A picture of chromosomes in order from large to small. It can show genetic disorders. |
A pedigree is? | a diagram showing a pattern of inheritance. |
A cow that is red with white splotches is an example of ? | codominace |
A red and white flower make pink flower offspring. This is an example of? | incomplete dominance |
What are the stages of mitosis and what happens in each stage? | I- interphase- DNA copied P-prophase- dna condenses and spindle is formed grabbing chromosomes M- homologous pairs move the the middle or equator A- pairs are separated to ends of cells T- chromosomes relax and nucleus reforms |
What is cytokinesis? | animal cells split by pinching off to form 2 new cells plant cells reform cell plate and wall |
What are the stages of meiosis and what happens in each stage? | I- interphase- DNA copied P 1-prophase dna condenses and CROSSING OVER occurs M 1-metaphase pairs line up at equator A 1- anaphase pairs separate T1 - chromosomes get ready to separate again REDO WITH OUT INTERPHASE PMAT (2) |
What are the common genetic disorders? Know what they do as well. | Cystic fibrosis- mucous clogs Down's syndroms- extra #21 chromosome Tay- sachs- breakdown nervous system Color blindness- sex linked Huntingtons- break down fat in brain Albinism- lack of pigment sickle cell- shape of blood cell changes. |
