In a given species of flowering plant, the colour of the seeds is exclusively determined by the colour of its seed coat. Seed coat colour in this species is governed by a nuclear gene with two alleles. The WHITE ( $W$ ) allele is dominant over brown ( $w$ ) allele. If a plant with brown seeds $(w w)$ is crossed as a female with pollen from a white seed $(W W)$ plant, what will be the seed colour and the genotype of the embryo in the resultant seeds obtained from this cross?

During the CoVID-19 pandemic, SARS-CoV2 virus mutated multiple times giving rise to many variants. What is the genetic material of the SARS-CoV2 virus?
