Answer:
1) Crossing over
2) Independent assortment.
Explanation:
Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.
The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.
This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Following gastrulation, the next major development in the embryo is neurulation, which occurs during weeks three and four after fertilization. This is a process in which the embryo develops structures that will eventually become the nervous system
<h2>Answer:</h2>
The offspring population will contains the desirable characteristics of both fantail pigeon and the fantail pigeon.
<h3>Explanation:</h3>
- The selective breeding is the planned breeding between two organism of the population with desirable properties to result in the new traits from both parents in the single next generation offspring.
- In this case, the offspring of the pouter pigeon and the fantail pigeon will contain the traits of pouter and it also has fantail.
- The new generation will be selective breed an it is from the breeding of intra specie organism. If breeding is inter specie than the offspring is most probably infertile.
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
So basically you will have to label the purple parent 1 and whatever gene that is then the same for parent 2 here is an example of a punnet square so maybe you can understand better
