A sperm is a haploid male gamete which fuses with the ovum to form the diploid zygot..Example:
A pure breeding tall plant of the P1 generation can be described as Homozygous tall plant : It carries two factors both of which are responsible for tallness (TT). Similarly, the dwarf plant of the P1 generation can be described as homozygous dwarf plant. It carries two factors, both responsible f..
Syngamy
It is the complete and permanent fusion of 2 haploid gametes to form a diploid zygote. When the 2 fusing gametes are morphologically and physiologically similar to each other, the process is called isogamy . Example: Monocystis When the 2 organisms themselves acts as h..
Sex Determination
During the formation of gametes, the females will have only one type of gametes, all with one X chromosome. However, the males will produce two types of gametes or sperms, half with X chromosome and half with Y chromosome. Thus the sex of a zygote is determined b..
Meiosis
This type of cell division occurs in reproductive cells (gametes). The male gamete is known as the sperm in animals and the female gamete is known as the ovum (egg). These gametes, after they are formed, have no future unless they unite to form a zygote..
Law of Segregation
This is also called the law of purity of gametes. According to this law, the gametes are pure for a particular trait. This is because the alleles of a pair separate during gamete formation and again come together after fertilization. Therefore, in each gamete..

Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells . In unicellular organisms like the protozoans, the gamete-producing individuals are called gametocytes. The gametes may be similar - i..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
