Non-mendelian Inheritance

1. According to Mendel’s law
phenotypical characteristics
would be determined by pair
of factors (alleles) that
separate independently in
gametes. What are the main
types of inheritances that are
exceptions to Mendel’s rules?
2. What is the genetic
condition in which the
heterozygous individual has
different phenotype from the
homozygous individual?
3. What is pleiotropy?
4. What are lethal genes?
5. What are multiple alleles?
Is there dominance in multiple
alleles?
6. What are gene interactions?
What are the three main types
of gene interactions?
7. What are complementary
genes? Does this inheritance
pattern obey Mendel’s second
law?
8. What is epistasis? What is
the difference between
dominant epistasis and
recessive epistasis?
9. In the hybridization of 2
genes (4 different alleles, 2 of
each pair) how does epistasis
affect the proportion of
phenotypical forms in the F2
generation?
10. What is polygenic
inheritance? How does it
work?
11. What is the most probable
inheritance pattern of a trait
with gaussian proportional
distribution of phenotypical
forms?
12. How to find the number of
pair of alleles involved in
polygenic inheritance using
the number of phenotypical
forms of the trait they
condition?
13. Why is sex-linked
inheritance an example of
nonmendelian inheritance?
14. What is mitochondrial
inheritance?
