The alternative experiment that is design to use animals as
participants instead of humans is called the analogue experiment. This type of
experimentation and research method is a way of having to produce behavior in a
state of abnormal-like that are being conducted to their participants.
Answer:
The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.
Explanation:
In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.
Thus, the correct answer is - option A.
DNA has to be divided into the two nucleotide chains that build it, so that new chains can be started to form. These new chains will connect with the old ones.
Bird skeletons are very delicate, and therefore, difficult to be preserved. The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.
