Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination for a population of plants.

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species  is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water  to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed  from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain  a particular plant would always breed true.

Additionally it prevent  the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get  weak and prone to diseases and infection. Because of poor resistant from lack of variation.

Explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
