The american curl is a breed of cate that has curly ears. the allele for curly ears is dominant. suppose a male cat with the heterozygous genotype is bred to a female cat with the homozygous recessive genotype. predict the ratio of kittens that will have the phenotype for curly ears. in your

a. write the genotypes for both parents; draw a punnet square that shows a cross between the 2 cats

b. write the phenotypic ratio of the offspring. if the cross produces six kittens, predict how many of them will have the curly ear phenotype

Cc * cc = Cc, Cc, cc, cc

Cc : 50%       cc: 50%

Three kittens will have the genotype for curly ears and three won't have the genotype for it.

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.'
