7.Understand why the phenotype of an individual does not always reveal its genotype – look back at number 3!!!
9.Understand and apply basic principles of heredity in crosses• perform Punnett square (predicts the ratios of the offspring in a cross)o• be able to apply rules of probability to compute expected genotypic or phenotypic ratios in a cross2¼= ¾
12.Understand that independent assortment is related to meiosis 13.Recall that not all genes assort independently & recall what linkage is • 14.Recall that sex is often determined by sex chromosomes & understand how sex inheritance works in mammals
15.Recall that not all organisms have chromosomes that determine sex • Sex of turtles are determined by temperature where eggs are hatched (environmental sex determination) 16.Understand that X-linked genes are special and be able to apply your understanding of how sex-linked inheritance works • X-linked genes are special (Female XX, Male XY)• Recessive x-linked genes are more likely expressed in males since they only have one X chromosome. oE.g. color blindness: a femalewould need the recessive an allele on both x chromosomes whereas a male only needs oneo
