Unit 7 Bio
| Question | Answer |
|---|---|
| phenotype is based on ____ and _____ | genotype and environmental factors |
| What is the syndrome where the genotype is X | Turner's syndrome |
| What is the syndrome where the genotype is XXY | Kleintifelter's syndrome |
| polyiplody | where chromosomes dont seperate properly, resulting in genetic disorders |
| Gregor Mendel | he found basic inheritance by breeding pea plants |
| Charles Darwin | theory of evolution and natural selection |
| Medelian Inheritance | basic inheritance, dominant and recessive allele |
| incomplete dominance | where the offspring is an inbetween of the two traits |
| codominance | where both traits are expressed at the same time |
| multiple alleles | a trait that is controlled by multiple alleles (example: blood type) |
| pleiotrophy | where a single gene affects multiple traits, like melanin |
| polygenic traits | a trait controlled by two or more genes |
| epestasis | where there is a gene that is dominant over another gene, thus making it not appear |
| karyotype | a map of all of a persons chromosomes |
| nondisjunction | where the chromatids do not seperate correctly during cell division |
| sex-linked inheritance | something that is inherited from the sex chromosomes |
| trisomy 21 | Down Syndrome, causes various mental and physical disabilities |
| two genes responsible for blood type | ABO and RH |
| what is ABO | it determines whether u have A, B, or O, A and B are codominant, and O is recessive |
| what is RH | it determines whether u are positive or negative, + dominant over - |
| agglutination | your blood starts to clump if u get the wrong blood type |
| hemolysis | a product of agglutination, your red blood cells rupture and u die |
| universal donor | O- |
| universal receiver | AB+ |
| A+ gives to, receives from | gives to A+, AB+, recieves from A+, A-, O+, O- |
| A- gives to, receives from | gives to A+, A-, AB+, AB-, receive from A-, O- |
| B+ gives to, receives from | gives to AB+, B+, receives from B+, B-, O-, O+ |
| B- gives to, receives from | gives to B-, AB-, AB+, receives from B-, O- |
| AB+ gives to, receives from | gives to AB+, receives from everyone |
| AB- gives to, receives from | gives to AB-, AB+, receives from AB-, A-, B-, O- |
| O+ gives to, receives from | gives to O+, A+, AB+, B+, receives from O+, O- |
| O- gives to, receives from | gives to everyone, receives from only O- |
| antibody | attacks foreign substances |
| antigen | the y-shaped proteins on the outside of the red blood cell |
| what antibodies does A blood have | anti-B |
| what antibodies does B blood have | anti-A |
| what antibodies does AB blood have | neither anti a or anti b antibodies |
| what antibodies does O blood have | both anti a and b antibodies |
| LOOK AT PEDIGREE PAGE AND MEMORIZE | DID U DO IT GNG? |
| what is cystic fibrosis and what type of disorder? | it is a defect in the gene that codes for a protein membrane, it causes excessive mucus and respriatory and digestive failure, it is autosomal recessive |
| albinism and what type of disorder? | it is the absence of melanin, and it is autosomal rescessive |
| Tay-Sachs and what type of disorder? | there is no enzyme to break down fatty substances, so it builds up in the brain and spinal cord and causes death by age 5, is common in Ashkenazi Jews (COOKED), recessive autosomal |
| galactosemia and what type of disorder? | your body doesnt have the enzyme to break down galactose, so it builds up in your liver and kidneys and can cause those organs to fail, autosomal recessive |
| What is Huningtons disease and what kind of disease is it | it is dominant autosomal, and it affects the neurodevelopment where you regress back to a newborn |
| What is achrondoplasia and what kind of disease is it | it is dominant autosomal, and you are a dwarf |
| Hemophilia and what kind of disease is it | it affects your ablitiy to clot blood, is sex linked |
| Sickle cell disease and what kind of disease is it | it is common in those of african descent, it prevents malaria and causes your red blood cells to be in a sickle shape, and it is CODOMINANT |
| Color blindness and what kind of disease is it | u cant see colors (no shizz sherlock) and it is sex linked |
