The Basics of Genetics…the passing of traits
Human Genetics It’s all in the….
Sex-linked traits. Sex chromosomes carry genes that code for traits other than gender. Traits determined by genes on the X chromosome are called sex-linked.
Two copies of each autosomal gene affect phenotype.
1. If two parents are both heterozygous for the tongue rolling gene, predict what genotype and phenotype their offspring may have. Roller allele is dominant.
Fnord babies ~ will be collected ~ In Fnords, orange (O) fur is dominant over blue fur (o). An orange fnord and a blue fnord mate, and produce 314 orange.

Parent 1Parent 2Offspring 1Offspring 2 Offspring 1 becomes Parent 1 for next generation This is what your data screen looks like from the simulation with the exception of Offspring 2. Offspring 2 is the new genotype of the person with whom you mated. It is not recorded in your data screen but you can collect that data by looking at that person’s new genotype after mating.

For example, if you determined that 1 indicated heterozygous that means that 1 codes for a male since the male genotype is XY. Therefore, 2 indicates homozygous since female is XX. 1 is M 2 is F

Then, determine how to represent homozygous dominant, heterozygous and homozygous recessive.

Parent 1Parent 2Offspring 1Offspring 2 Offspring 1 becomes Parent 1 for next generation Take the following data and complete a pedigree using the previous example as an outline for how to proceed. Below is the data.

Parent 1Parent 2Offspring 1Offspring 2 Translate the data for the first gene into the sex of the individual. For example, if you determined that 1 indicated heterozygous that means that 1 codes for a male since the male genotype if XY. Therefore, 2 indicates homozygous since female is XX. 1 is M 2 is F

2 is homozygous dominant 1 is heterozygous 0 is homozygous recessive MaleFemale Typically, male is represented by a square and female by a circle. Now, complete a pedigree that represents the genotype of each individual Parent 1Parent 2Offspring 1Offspring 2
