Genetics Review. In pigs, the dominant trait is short snouts. Using the letter “N,” write the three possible genotypes for pigs. Then, write the matching phenotypes for those genotypes. NN = Short snout Nn = Short snout nn = Long snout.

Dominant traits overpower or cover-up the recessive trait. Dominant traits occur more often in an organism.
The only way for a recessive trait to show up is for BOTH alleles in the organism to be recessive. The recessive traits have to “gang up” together to show through. For example: ff – both alleles (letters) in the genotype are recessive.

In tigers, long claws are a dominant trait over short claws. A female tiger, who is heterozygous, has offspring with a male tiger who has short claws. Complete the Punnett Square.
In leprechauns, having pointy ears is a dominant trait. A female leprechaun that is homozygous for the dominant trait has offspring with a male leprechaun who is homozygous for the recessive trait. Complete a Punnett square to show their possible offspring.
In tulips, the color red is a recessive trait and the color white is the dominant trait. A white tulip (Ww) is crossed with a red tulip. Create a Punnett Square to predict the color of the plants created from the cross.
In the Simpson family, yellow skin is the dominant trait. If Lisa (YY) marries a boy from another town who has pink skin (yy), what would be the probability of their offspring having yellow skin? Create a Punnett Square to show your work.
Two dogs have a litter of puppies. All of the puppies are heterozygous, showing the dominant trait of brown hair. What must the genotypes of the parents be?
In mice, the dominant color is brown. The recessive color is tan. Two mice, that are both brown, have a baby mouse that is tan. What must the genotypes of the parents be for this to occur?
