Most invertebrates leave their young to fend for themselves while vertebrates help their young till they are ready
In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings.
Answer:
Incorrect
Explanation:
Climate change, pesticides put monarch butterflies at risk of extinction. A new study finds that monarch wings are getting larger, possibly because climate change has forced the butterflies to travel longer distances as breeding grounds shift farther north!
Good Luck on the test!
