For biologists and genetics enthusiasts, the most commonly-known form of inheritance can be attributed to the learnings established by Gregor Mendel. From his studies, we are aware of the three core principles – dominance, segregation, and independent assortment – that govern how genes are passed down from generation to generation. However, although this model ‘rules’ much of inheritance as it stands today, a significant body of evidence shows us that there is more than meets the eye in terms of how genetic material is inherited during different conditions. This blog post will delve into Non-Mendelian Genetics forms and explore its various implications on modern biology research!

GENETICS PRACTICE 2:
1.In radishes, the gene that controls color exhibits incomplete dominance.
2.Crosses between a yellow rat and a yellow rat always produce yellow rats. Crosses between a white rat and a white rat always produce white rats. But crosses of a white with a yellow produce a cream rat. What are the genotype and phenotype ratios if you cross two creams?
3.In humans, the allele for albinism (lack of pigment) is recessive to the allele for normal skin pigmentation. If two heterozygous parents have children what is the chance that a child will be albino?

4.If normal parents have an albino child, what is the probability that their next child will be normal for pigment?
5.Achondroplasia (dwarfism) is caused by a dominant gene. A woman and a man both with dwarfism marry. If homozygous achondroplasia results in death of embryos, list the genotypes and phenotypes of all potential
6.The genes for hemophilia are located on the X chromosome. It is a recessive disorder. List the possible genotypes and phenotypes of the children from a man normal for blood clotting and a woman who is a carrier. (HINT: You have to keep track of what sex the children are!)
