Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best
Nina [5.8K]

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:<u> vestigial structures</u>.

Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.

  • These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.

  • These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.

  • The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.

Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

Each of two parents has the genotype green divided by brown​, which consists of the pair of alleles that determine eye color​, a
Liula [17]

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

               Mother:      Brown                                 Green

Father↓  

Brown                      Brown-Brown                 Brown-Green

Green                      Brown-Green                  Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%
