1. about 70% of americans perceive a bitter taste from the chemical phenylthiocarbamide (ptc). the ability to taste this chemical results from a dominant allele (t) and not being able to taste ptc is the result of having two recessive alleles (t). albinism is also a single locus trait with normal pigment Practice genetics problems dihybrid crosses adapted from practice genetics problems, kansas state university, available at...

Mendel's monohybrid crosses

Mendel's monohybrid crosses 1. here we will summarize mendel's first series of crosses. in these crosses, he started with pure breeding peas that always produced the same color flowers. one strain produced purple flowers, the other white flowers. these pure-breeding plants were the parental or p generation. the This is the outcome that mendel found when conducting dihybrid crosses. the f2 always shows new combinations of the 2 alleles for the 2 traits.

Mendelian genetics gregor mendel was an austrian monk who experimented with pea plants during the mid 1800s. although mendel knew nothing of genes, alleles, chromosomes or dna at that time, he observed that heritable traits were and could be selectively passed on in the pea plants he studied. he theorized that "units" of heritable...
