INHERITANCE
INHERITANCE

4. Mendelian inheritance refers to certain
patterns of how traits are passed from
parents to offspring. These general
patterns were established by the
Austrian monk Gregor Mendel, who
Austrian monk Gregor Mendel, who
performed thousands of experiments
with pea plants in the 19th century.

6. LAW OF DOMINANCE
LAW OF DOMINANCE

7. Mendel's law of dominance states that:
“When parents with pure, contrasting
traits are crossed together, only one
form of trait appears in the next
generation. The hybrid offsprings will
generation. The hybrid offsprings will
exhibit only the dominant trait in the
phenotype.” Law of dominance is known
as the first law of inheritance.

LAW OF SEGREGATION

11. During gametes formation When an
organism makes gametes, each gamete
receives just one gene copy, which is selected
randomly. This is known as the law of
segregation. A Punnett square ( Used for
can be used to predict
genetic cross table) can be used to predict
genotypes (allele ( gene Variation )
combinations ) and phenotypes (observable
traits) of offspring from genetic crosses.

13. LAW OF INDEPENDENT
ASSORTMENT
ASSORTMENT

14. Mendel's law of independent
assortment ( classified ) states that the
alleles of two (or more) different genes
get sorted into gametes independently
of one another. In other words, the
of one another. In other words, the
allele a gamete receives for one gene
does not influence the allele received
for another gene.

15. Genes for the different traits assort
independent of each other during
gamete formation which is selected
randomly.

16. MULTIPLE ALLOTS
AND BLOOD
AND BLOOD
GROUPS

17. ALLELS ( ALLOTS )
Alleles are the pairs of genes occupying a
specific spot called locus on a chromosome.
Alleles are a pair of genes that occupy a
specific location on a particular chromosome
and control the same trait.

18. Typically, there are only two alleles for a gene
in a diploid organism. When there is a gene
existing in more than two allelic forms, this
condition is referred to as multiple allelism.
Allelism refers to any of the several forms of a
gene. These genetic variations arise usually
through mutation and therefore are
responsible for hereditary variations.

21. Multiple alleles are three or more alleles for a
particular gene. Multiple allelism
(biology definition):
(biology definition):
The condition of the presence of multiple
alleles. An example of multiple alleles is the
ABO blood group system in humans.
