Question

Based on these concepts, choose statements that correlate Mendel's four postulates with what is now known about genes, alleles, and homologous chromosomes. Select the six correct statements..
1. Dominant alleles can become codominant alleles during mitosis.
2. Some possible gametic combinations are formed with higher probability if dominant alleles take part in meiosis.
3. Alleles segregate from each other during gamete formation at anaphase I.
4. Some genes have dominant and recessive alleles.
5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
6. During mitosis and meiosis, when chromosomes are visible in their characteristic shapes, members of a homologous pair have different sizes and exhibit opposite centromere locations.
7. Unit factors occur in pairs.
8. One gene pair separates independently from other gene pairs.
9. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
10. Some gene pairs on nonhomologous chromosomes can aggregate after separation and mitosis or meiosis would stop.

Answer 1

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.
