Non-Mendelian Genetics Flashcards
What are the five types of non-Mendelian inheritance
Incomplete dominance
Codominance
multiple alleles
polygenic inheritance
sex linked traits and/or sex influenced
What is incomplete dominance?
neither allele us dominant over the other
how is incomplete dominance expressed?
appearance appears “blended”
What is codominance?
condition in which both alleles are expressed equally because they have equal dominance
How is codominance expressed?
can both be seen present, looks “spotted”
True or False: In codominance neither allele is dominate over the other
true
What is Pleiotropy
when one gene influences multiple traits
What is fragile X?
A family of genetic conditions associated with the X chromosome
What does non-nuclear inheritance describe?
the inheritance of genes from structures other than the nucleus
True or False: Maternal inheritance is a non-nuclear inheritance
True
what is non-mendelian inhertiance
not determined by a dominate or recessive trait instead traits can be governed by more than one gene
