This document discusses several forms of non-Mendelian inheritance including incomplete dominance where traits show a combined phenotype, co-dominance where offspring exhibit both parental traits together, multiple alleles where more than two alleles can code for a trait, maternal and paternal effects where the parent's environment or genotype influences the offspring's phenotype, epigenetic inheritance involving modification to genes or chromosomes early in development, and gene conversion being a DNA recombination process that transfers sequence information between DNA helices.

1. Non-Mendelian
Inheritance

2. Non-Mendelian
Inheritance
 It is a term used to refer to any
pattern of inheritance in which traits
do not segregate in accordance
with Mendel’s Laws

3. Incomplete Dominance
 A form of intermediate inheritance
in which one allele for a specific
trait is not completely dominant
over the other allele.
 This results in a combined
phenotype

5. Co-Dominance
 A cross between organisms with
two different phenotypes produces
offspring with a third phenotype in
which both of the parental traits
appear together.

6. Multiple Alleles
 Involves more than just the typical
two alleles that usually code for a
certain characteristic in a species

7. Maternal Effect
 A situation where the phenotype of
an organism is determined not only
by the environment it experiences
and its genotype, but also by the
environment and genotype of its
mother
 Occurs when an organism shows
the phenotype expected from the
genotype of the mother

8. Paternal Effect
 A phenotype results from the
genotype of the father
 The genes responsible for these
effects are components
of sperm that are involved
in fertilization and early
development.

9. Epigenetic Inheritance
 Modification occurs to a nuclear
gene or chromosome.
 This occurs during
spermatogenesis, oogenesis, and
early stages of embryogenesis

11. Gene Conversion
 One of the major forms of Non-
Mendelian Inheritance
 It is a reparation process in DNA
recombination, by which a piece of
DNA sequence information is
transferred from one DNA helix
(which remains unchanged) to
another DNA helix, whose
sequence is altered.
