During mammalian fertilization, two haploid gamete cells fuse to generate a diploid cell called a zygote. Each parent donates a set of chromosomes, yielding offspring that carry both a maternal and a paternal set of chromosomes. Each chromosome within the maternal set has a correlative chromosome within the paternal set that encodes for the same hereditary characteristics. These corresponding chromosomes are called homologous pairs. Diploid mammalian cells have

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
