Why did dna technology lead to more use of cladistico?
a. it showed that the linnaean system was very accurate,
b. it showed that gene flow happens between populations,
c. it showed that different looking animale are actually related.
d. it showed that most traits result from genetic drift

Acertain species of fish can have either long or short fins. the allele for long fins is dominant over the allele for short fins. a heterozygous, long-finned fish is crossed with a homozygous, short-finned fish. of the offspring, will have long fins and be , and will have short fins and be .

Awave has a wavelength of 15 mm and a frequency of 6 hertz. what is its speed?

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
