White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with homozygous recessive canary. What ratio of the offspring homozygous recessive?

2:4 (this means that there would be 2 homozygous recessive canaries out of a total of 4 canaries produced; or 50%)

The nurse should include dirahea, dry mouth, vomiting, decreased sex drive, lack of coordination, tingly feelings, impotence, or difficulty having an orgasm.. good luck

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
