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.
