Difference between sexual and asexual reproduction
|
asexual, 1 parent produces clone, genetically identical to parent. Sexual there is meiosis, formation of gametes, and fertilization.
|
|
|
2 parts of meiosis
|
meiosis1 homologues are seperated from each other
Meiosis 2 sister chromatids are seperated from each other. 4 haploid daughter cells. |
|
|
spermatids
|
four male haploid cells after meiosis
|
|
|
sperm
|
mature male gamete
|
|
|
primary oocyte
|
female diploid germ cell
|
|
|
seondary oocyte
|
larger of 2 daugher cells
|
|
|
polar body
|
smaller of the 2 daughter cell, eventually have 3 that die
|
|
|
ovum
|
mature female gamete, only 1 produced per germ cell
|
|
|
genetics
|
study of inheritance and variation of organisms
|
|
|
What are genes and where are they located
|
genes are units of info. about traits. Specific location on chromosome called locus.
|
|
|
Sex linked
|
a gene, usually on x since it is larger, that in males only has one allele, which is always expressed in males.
|
|
|
Punnett square
|
method of prediction the offspring based on genotype of partents
|
|
|
pedigree
|
chart of genetic connections among individuals
|
|
|
Process of Dna replication
|
bonds broken with enzymes, new nucleotides bond with parents, producing 2 identical dna molecules
|
|
|
Polymerases and ligases
|
P-enzymes that attache free nucleotides to parent strands and L- enzymes that fill tiny gaps to form a continuous strand.
