Question | Answer |
haploid | 1n - sperm and egg 1 chromosome |
diploid | 2n -n=23 in humans two chromosomes |
50% cost of sex | fitness? |
homologues | the members of a pair of chromosomes are this |
phases of the cell cycle | G1-S(synthesis)-G2-M(Mitosis) |
Red Queen Hypothesis | the advantage of sexual reproduction at the level of individuals, and the constant evolutionary arms race between competing species. For an evolutionary system, continuing development is needed just in order to maintain its fitness relation to other spec. |
Interphase | G1-S-G2 G1- decide to divide S- chromosomes are replicated G2- Cell synthesizes proteins that are necessary for chromosome sorting and cell division M- first part is mitosis divide one cell nucleus into two cell nuclei |
Prophase | chromosomes have already replicated and then join to become sister chromotids |
Prometaphase | miotic spindle is ready adn sister chromatids attach to it |
metaphase | the sister chromatids are alligned in a row along the metaphase plate |
anaphase | connections between sister chromatids are broken and sepereate |
telephase | the chromosomes have reachedtheir respective poles nad decondense |
cytokinesis | cleavage furrow in animal cells cell plate in plants |
sex linked | found on one sex chromosome but not on the other |
