The question is incomplete. The complete question is as following:

Answer:

vestigial structures

Explanation:

A "vestigial structure" or "vestigial organ" are defined as the organs that no longer have any function in the organisms' body but had an important role in past.

<em>Pelvis and femur are thigh bones in humans which helps them in walking but in whale's pelvis and femur are considered as vestigial structures. </em>

The pelvis and femur in whales, are the inherited structure from ancestors and shows evidence for evolution on the basis of natural selection.

Hence, the correct answer is vestigial structures.

Setler [38]

Answer:

Explanation:

Al igual que la mitosis, la meiosis es una forma de división celular eucariota. Sin embargo, estos dos procesos distribuyen el material genético entre las células hijas resultantes de formas muy diferentes. La mitosis crea dos células hijas idénticas, cada una de las cuales contiene el mismo número de cromosomas que su célula madre.

Which is an example of codominance? (1 point)

Dafna11 [192]

Answer:

roan coat color in horses

Explanation:

Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.

An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.
