Question

At the second metaphase of meiosis Chromosomes have single chromatids and align in homologous pairs. Chromosomes have single chromatids and do not align in homologous pairs. Chromosomes have two chromatids and align in homologous pairs. Chromosomes have two chromatids and do not align in homologous pairs. Chromosomes have two chromatids and are separating to opposite poles of the cell. Incomplete dominance at a single locus always results from the mutant protein having partial function results in a self-crossed population with identical phenotypic and genotypic ratios cannot be distinguished from epistasis can generate a true breeding intermediate phenotype gives the same genetic ratios as 2 unlinked genes each showing complete dominance

Explanation / Answer

1. The correct option is e. In the second metaphase of meiosis, the chromosomes have two chromatids and are separating to opposite poles of the cell which is very similar to mitosis.

2. The correct option is d. This is because in incomplete dominance both the alleles are unable to express themselves completely. Thus resulting in an F1 hybrid with an intermediate phenotype of the two parental phenotype.
