Pigeons have two alleles of a single gene that determines whether they have feathers on their lower legs. The alleles are called no grouse (associated with the featherless phenotype) and grouse (associated with feathery legs). Suppose a pigeon that is homozygous for the no grouse allele mates with a heterozygous pigeon. What is the expected frequency of the homozygous no grouse GENOTYPE in the offspring?

What would be the most likely result if the ph of the stomach were increased to 5

Plz fast biotechnology is a growing field of applied biology. many crops such as corn have been engineered to be resistant to herbicides. therefore farmers can spray these chemicals to kill weeds growing near the crop without worries of killing the crop itself how does this type of biotechnology work? a. by changing the genetic make up of the crops. b. by causing the crops to kill the weeds. c. by changing the type of crops used. d. by changing the location of the crops.
