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.
Answer:
Each mutant would be mated to wild type and to every other mutant to create diploid strains. The diploids would be assayed for growth at permissive and restrictive temperature. Diploids formed by mating a mutant to a wild type that can grow at restrictive temperatures identify the mutation as recessive. Only recessive mutations can be studied using complementation analysis. Diploids formed by mating two recessive mutants identify mutations in the same gene if the diploid cannot grow at restrictive temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at restrictive temperature (complementation).
Explanation:
Recessive mutations are those whose phenotypic effects are only visible in homo-zygous individuals. Moreover, a complementation test is a genetic technique used to determine if two different mutations associated with a phenotype colocalize in the same <em>locus</em> (i.e., they are alleles of the same gene) or affect two different <em>loci</em>. In diploid (2n) organisms, this test is performed by crossing two homo-zygous recessive mutants and then observing whether offspring have the wild-type phenotype. When two different recessive mutations localize in different <em>loci</em>, they can be considered as 'complementary' since the heterozygote condition may rescue the function lost in homo-zygous recessive mutants. In consequence, when two recessive mutations are combined in the same genetic background (i.e., in the same individual) and they produce the same phenotype, it is possible to determine that both mutations are alleles of the same gene/<em>locus</em>.
Could you ask again but with more details? I do not understand.
