Who is known as "the father of genetics"?

________ Allele- An allele that covers another allele

_________ Allele- An allele that is covered, or hidden by another allele

Select all answers that are correct for Mendelian genetics (normal dominant/recessive relationship between the alleles).

• The dominant allele is ALWAYS seen when a dominant allele is present

• The recessive allele is ALWAYS seen when a recessive allele is present

• TWO recessive alleles must be present for the recessive allele to be seen

• TWO dominant alleles must be present for the dominant allele to be seen

Which of the following are correct. There may be more than one correct answer.

• an upper case letter = the recessive allele

• a lower case letter = the recessive allele

• an upper case letter = the dominant allele

• a lower case letter = the dominant allele
