Answer:
Explanation:
Mendel four postulate is Principles of Paired Factors, Principle of Dominance, Law of Segregation which is Mendels First Law of Inheritance and Law of Independent Assortment which is Mendel’s Second Law of Inheritance.
The six possible outcome are,
3. Alleles segregate from each other during gamete formation at anaphase I gene assorts independent of each other during gametes formation.
4. Some genes have dominant and recessive alleles. Allele of a gene can either be dominant or recessive in its form
7. Unit factors occur in pairs , allele of a gene occur in pair
Dominant alleles can become codominant alleles during mitosis, when two allele both finds expression in the phenotype of an organism they are codominant
8. One gene pair separates independently from other gene pairs independent assessment of gene.
5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
