If blue and red true-breeding flowers are mated and result is all purple offspring, what inheritance pattern would this be indicative of?

• Codominance

• Dominance

• Incomplete dominance

• Multiple Alleles

Can a human male be a carrier of red-green color blindness?

• Yes, males can be carriers of red-green color blindness, as color blindness is autosomal dominant

• No, males cannot be the carriers of red-green color blindness, as color blindness is X-linked

• No, males cannot be the carriers of red-green color blindness, as color blindness is Y-linked

• Yes, males can be carriers of red-green color blindness, as color blindness is autosomal recessive

True or false; The number of chromosomes is reduced from n to 2n during meiosis.

• True!

• False

P Generation -> _________ -> F2; Fill in the blank
