First blank: The mobility of their hosts same goes for the second one :)
Can you please take a picture of the question. Because I don’t understand it in this format
Good job for getting the answer
The recombinant offsprings are normally the offsprings containing a combination of the parents allele, result in a genotype that differs from both parents genotype. The phenotype May be different as well although it is likely that the phenotype could be the same as the parents, as seen in the case of heterozygous dominant having the same phenotype as homozygous dominant.
