inheritance
Biology ch 13
| Term | Definition |
|---|---|
| Father of Genetics | Gregor Mendel |
| what did gregor mendel do | he studied inheritance patterns in pea plants, |
| heredity | passing of traits from parent to offspring |
| alleles | two forms of a gene that are represented by capital or lower case letters |
| dominant | stornger of the two alleles expessed in the hybirid, R |
| recessive | gene that is masked by the domimant, r |
| genotype | gene combination for a trait (RR,Rr,rr) |
| pheontype | the physical feature resulting from a geontype (red or white) |
| homozygous genotype | gene combination involving the same kind of genes, aka pure |
| heterozygous genotype | gene combination of one dominant and one ressive allele aka hybrid |
| punnett squares | used to determine the probability of having a certian type of offspring when given the alleles of the parents |
| momohybrid cross | cross involving a single trait |
| P1 | the parental generation in a breeding experiment |
| F1 | the first generation offspring in a breeding experiment |
| F2 | the second generation offspring in a breeding experiment |
| Law of Dominance | some genes of a pair of genes can dominate over the other gene, such that the individual appears to only have one of the allelse |
| Law of Segreation | individuals have two genes for each trait, one from the mother and one from the father during sperm and egg formation these two genes separate so that each spder or egg has only one gene |
| Law of Independent Assortment | during reproduction, the genes to different traits sort independently of each other in the egg and sperm |
| incomplete dominace | when the heterozygote is intermediate to the homozygotes. Cross a red snapdragon with a white snapdragon and the offspring are pink. |
| codominance | where both alleles are expressed. EX: A blood crossed with B blood creates AB blood |
| Espistasis | when one gene inteferes with an allele to another gens. |
| incomplete dominance | the heterozygous condition resluts in an intemediate third blended phenotype |
| codominance | both alleles of a gene are expressed equally |
| multiple alleles | when more than two different alleles exist for the same trait |
| Rh factor | an inherited trait taht refers to a specific protien found on the surface of red blood cells. if you blood has the protien then your positive and if you don't have it then youre negative |
| multifactorial traits | determined by interaction between a gene or gens and the environment |
| polygenic traits | the inheritrance patter is controled by two or more genes each with two alleles |
| linked genes | genes that are located on the same chrosome, and are often inherited togehter |
| universal recipent of blood | AB+ |
| universal donor of blood | O- |
| sex-linked traits | a gen found only on the x chrosome and not the y |
| barr body | the inactive x chrosome of mamals |
| agglutination | when blood antigens are mixed with corresponding antibodies |
| pedigree | a graph or chart on studing a genetic syndrome |
| inheritance of mitochondrial DNA | only inherited by moms egg, passes it to all of their offspring |
