1. Nemo decides to expand his business by breeding seahorses. Nemo has an Orange seahorse with a green snout, but he finds out that Orange seahorses with yellow snouts were in high demand. Nemo closed shop early and swam deep in to the ocean where seahorses are found. He found 9 baby seahorses, 7 of the babies were red with yellow snouts and 2 of the babies were orange with green snouts. Nemo caught a red seahorse with a yellow snout. He knew that his seahorse was heterozygous for skin colour and recessive for snout colour. His orange seahorse with green snout has a homozygous trait for skin colour and a heterozygous trait for snout colour. Using a punnett square, show the different genotypes that can be produced from this cross. Give the probability of Orange seahorses with Yellow snouts.
2. On one of Nemo's trips in to the deep ocean, he found a seahorse named Charlie that blew square bubbles from his mouth. Nemo asked the seahorse about this trait and found that blowing square bubbles is a genetic disorder caused by a recessive chromosome. During his questioning Nemo also found that Charlie's mother, 3 brothers and 2 sisters also have the trait , but his father did not. On Charlie's mother's side of the family, his grandmother also had the trait but his grandfather did not.
--> Draw the correct pedigree for this seahorse's (Charlie's) family.
--> How do you draw the pedigree?
