Define independent assortment within the framework of meiosis. What impact does homologous recombination have on the principle o
Paul [167]

Answer:

The law of independent assortment states that the different genes get separated independently of each other and gets assorted into gametes to produce different combination of genes.

It was formulates by famous scientist G. Mendel based on his work on peas.

For example, in a traditional dihybrid cross of true breeding round and yellow seed plant with wrinkled and green seed plant, F2 generation show four different combinations of phenotype:

  • round and yellow
  • round and green
  • wrinkled and yellow
  • wrinkled and green

It shows that genes for round and yellow were independently inherited and genes for wrinkled and green were independently inherited. Else, new combinations could not be observed.

Homologous recombination is an event that takes place in prophase I during meiosis. The genetic material is exchanged between the non-sister chromtids of homologous chromosomes. It adds into the genetic variation within a population by producing more combination of genes in the gametes.

It does not violate the law of independent assortment as the genes were independently assorted. It only helps in producing more combinations of genes.

How are vestigial structures an example of evidence of evolution?
lutik1710 [3]
They provide evidence of genes coding for structures that are present not because they are useful, but because they were once useful to an ancestor. 

<span>One example is the plantaris muscle. This is a long, thin muscle in the human foot and calf that serves no significanl purpose in humans ... in fact, it is regularly removed by doctors harvesting muscle tissue to use in reconstructive heart surgery, because its removal leaves no loss of function in walking or balance. </span>

<span>However this same muscle is found more fully developed in the feet and calves of other primates. It is the muscle used for grasping with the feet.</span>
