asexual reproduction - answer-directing cells to divide and develop into new tissues
and organs without a partner
sexual reproduction - answer--takes more time and energy than asexual reproduction
-genetically diverse offspring
-requires fertilization
-requires haploid gametes
-mating
most plants and animals produce_______ - answer-gametes called eggs and sperm
Meiosis - answer-nuclear division that forms haploid cells
Meiosis I - answer-diploid cells divide to create 2 haploid cells, each with one of the
homologous chromosomes
Meiosis II - answer-2 haploid cells divide to form 4 haploid cells, which develop into
eggs or sperm
Prophase I (Meiosis) - answer--chromosomes condense
-nuclear envelope breaks down
-spindle fibers start to form (microtubules)
-crossing over occurs
, Metaphase 1 (Meiosis) - answer-Pairs of homologous chromosomes move to
metaphase plate
Anaphase I (Meiosis) - answer-homologous chromosomes separate and move to
opposite poles of the cell
Telophase and Cytokensis (Meiosis) - answer--chromosomes gather at poles of the cell
-cytoplasm divides
Prophase II (Meiosis) - answer--2 cells
-a new spindle forms around the chromosomes
Metaphase II (Meiosis) - answer-chromosomes line up at the metaphase plate/equator
Anaphase II (Meiosis) - answer--2 cells
-centromeres divide
-chromatids move to opposite poles of the cells
Telophase II and Cytokinesis (Meiosis) - answer--goes from 2 cells to 4 cells
-nuclear envelope forms around each set of chromosomes
-cytoplasm divides
Asexual organisms - answer--New alleles must occur independently
-can't be passed around and mixed with the genetic make up/ different alleles of other
organisms
Sexual organisms - answer--populations can accrue new beneficial alleles in a shorter
period of time than asexual organisms
-organisms in a population can share beneficial alleles
