Genetics AGAIN

     This class we learned about co-dominance, incomplete dominance, and sex linked genes. Co-dominance is when a single gene has more than one dominant allele and when an individual is heterozygous, both alleles will be shown. An example of this is blood type, type A and B are both dominant, so an individual with both will have AB blood, as opposed to one or the other. Incomplete dominance. Incomplete dominance is when a heterozygous offspring shows a mixture of the two alleles. For example, a red flower and a white flower have an offspring which is a pink flower. Sex-linked is when, for example, an x linked gene is passed onto a son, the son will always show that trait, even if it is recessive, because he doesnt have another X chromosome to show the dominant trait, he has a Y chromosome, however if it is passed to a daughter it doesn't always show.
