The Life Cycle
Terms
Genes
Locus
Genetics
Inheritance
Allele
Haploid cell
Karyotype
Diploid cell
Sexual reproduction (diploid)
2 parents give rise to offspring with a unique combination of genes, offspring varies genetically
Meiosis
Meiosis I
Prophase I
dyads/homologous chromosomes pair
Metaphase I
dyad pairs line up at metaphase plate
Anaphase I
homologous pairs of chromosomes/dyads separate
Telophase I and Cytokinesis
generates 2 cells
each cell has dyad of each chromosome number
Meiosis II
Anaphase II
break down cohesin to separate the dyad into monads/sister chromatids
Telophase II
generates 4 cells, each 1n (monad)
Metaphase II
single dyads at metaphase plate
Prophase II
single dyads for each chromosome
Interphase
Growth and DNA replication
Diploid cell with 2 chromosomes
Variation during meiosis
Random fertilization
Crossing over
Independent assortment
Asexual reproduction (haploid)
sole parent passes exact copies of genetic information to offspring through mitosis
Alternation of generation
haploid generation then diploid generation (alternates each generation)
