Suppose in a flower of mustard, each microsporangium posses 20 pollen mother cell then the total number of male gametes formed by this flower will be View Solution Assertion : In honeybee, female is diploid and male is haploid. Reason : Gametes are formed by meiosis in female and by mitosis...
Formation Gametes are formed by _meiosis_, a special type of cell division, which involves one round of DNA replication and two rounds of cell division. It results in the formation of four haploid cells, each having half of the number of chromosomes as compared to somatic/stem cells. These...
Gametes: Gametes are haploid sex cells. The male gamete, sperm is produced from the testes and the female game ovum is produced from the ovary. The fusion of gametes results in the formation of a zygote. Answer and Explanation:1 Gametes are produced by meiosis. Meiosis, also called reductio...
18.You'll remember from biology that gametes are haploid cells, meaning that they only have one set of chromosomes, and are formed by meiosis. 你会记得生物学中配子是单倍细胞,这意味着它们只有一套染,是由减数裂形成的。 「Crash Course 解剖生理学篇」 19.Do I need to mention the fact that ...
Reason: Gametes are formed by meiosis in female and by mitosis in male. a) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion. b) If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion. c) If ...
Briefly describe, in your own words, how the single cell formed at fertilization differentiates into different types of cells. How is the mitotic phase different from meiosis? Explain why all of the cells of your body that have 23 pairs of chromosomes are identical in their genetic make-up. ...
Meiosis, which occurs only in the formation ofgametes, is a specialized form of cell division. 仅仅发生在配子形成中的减数分裂是一种特殊形式的有丝分裂. 辞典例句 The fusion of twogametesthat are not closely related. 异系结合无密切亲缘关系的两种生物的结合. ...
What are the two type of gametes? Gametes: In sexually reproducing organisms, body cells are diploid, meaning that they have two sets of chromosomes. Meiosis is the process through which gametes form, and it cuts the number of chromosomes in half. The gametes that are formed by meiosis are...
They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis. Limited information is available about these male gametic cells, beyond observations by electron microscopy, because each is surrounded by the cytoplasm of ...
In animals,sexual reproductionencompasses the fusion of two distinctgametes(sex cells) to form a zygote. Gametes are produced by a type of cell division calledmeiosis. In humans, gametes are produced in the male and femalegonads. When gametes unite infertilization, a new individual is formed. ...
