Max visited the Wild Things (pictured above). In Wild Things, XX individuals produce eggs and are female; XY individuals produce sperm and are male. Several traits in Wild Things are genetically based. the length of horns is genetically based: HH and Hh = curved horns, hh = straight horns having claws on the feet is determine by an X-linked gene. XB is dominant and results in absence of claws; Xb is recessive and results in claws. A female who is heterozygous for both traits and a male without claws who is heterozygous for horns have offspring. Answer the following questions based on this couple. You should start by determining their genotypes and setting up the Punnett squares. The probability that their first offspring would have curved horns is . The probability of their first child having straight horns and NO claws is . The probability of their first child being a female with claws is . Each parent only passes on one of the two alleles they have (Mendel’s Law of Segregation), and the way that the alleles for horns is passed on does not impact the way the allele for claws is passed on (Mendel’s Law of Independent Assortment). These two laws are the result of the way that works.
