When a dominant gene is paired with a recessive gene, the characteristic associated with the dominant gene will be expressed.
Explanation:
Recessive gene is not expressed when paired with a dominant gene as the alleles of the dominant trait will mask the recessive gene expression. The trait appearing in the offspring will be the dominant type. In other words, the dominant allele would dictate the protein to get appeared in the offspring.

Answer:
answer b is the correct of this question
In a process called <u>Synapsis</u>, paired homologous chromosomes align randomly at the cell equator. This occurs during stage <u>prophase I</u> of cell division.
Synapsis refers to the pairing of the homologous chromosomes in the meiosis occuring in the reproductive cells. Meiosis I is divided into four phases called the prophase I, metaphase I, anaphase I and the telophase I. Prophase I is the longest phase of meiosis which is further divided into leptotene, zygotene, pachytene, diplotene and diakinesis.
During the zygotene of meiosis I, the paring of the homologous chromosomes called the synapsis takesplace which is facilitated by the protein structure called the synaptonemal complex. The paired chromosomes are called the bivalents. This facilitates the homologous recombination.
