The following pedigree concerns the autosomal recessive disease phenylketonuria (pku). the couple marked a and b is contemplating having a baby but is concerned about the baby having pku. what is the probability of the first child having pku? unless you have evidence to the contrary, assume that a person marrying into the pedigree (i. e., not a descendant of the two parents at the top of the pedigree) is not a carrier. the filled-in individuals have pku.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

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.'

i believe the answer is snake.

idk what happened..you tell
