Animal cell gets
cleavage furrow
Meiosis 1
reduce
Meiosis 2
equal
Cytokinesis occurs simultaneously during
telopahse 1 of meisos 1
law of independent assortment
hybrid for traits not on the same chromosome
Dihybrid cross
Hybrid for traits that are not on the same chromosome
Incomplete dominance
blending
black and white make grey
Code dominance
both show
black and white makes black and white spots
46 chromosomes =
44 autosomal
2 sex
Sources of variation are
crossing over and recombination
The result of crossing over is
recombination
Stomatic cell
In females one chromosome one is active the other one is in active
Genomic imprinting
changes in the phenotype depending on whether the trait is inherited from the mother from the father
Extranuclear genes located ..
in mitochondria and chloroplasts
Pleitropy
gene responsible for traits in several body systems
Three parts to DNA construction

What works as a catalyst in DNA replication
replication bubbles
DNA polymerase
catalyzes elongation of new DNA strand
