Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. pink is the heterozygous condition in a trait that shows incomplete dominance. if pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?

a) 0%
b) 25%
c) 50%
d) 100%

0%

A cross between Rr plants and rr plants will yield a ratio of 2Rr:2rr. If Rr represents pink flowers, then none will be red.

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.'
