Question

Over Prophase 1 & Prophase 2 and independent Assortment in Prophase 1 only Sperm fertilizing erg in Telophase 2 and zygote formation after Cytokinesis 2 Question 3 1 pts Pg 99. Why is it essential that each gamete receive only one set of chromosomes, in other words. why must gametes be haploid? Because a haploid gamete can then fuse with a diploid egg or diploid sperm which promotes fertilization and development of a zygote. Because when gametes fuse in fertilization, the resulting zygote will then have a complete set of homologous chromosome pairs. Offspring from sexually reproducing organisms will always have twice as many chromosomes as their parents due to fertilization Gametes are not haploid, they are diploid so that a zygote will develop with the right number of chromosomes in its cells Question 4 0.5 pts Da 09 Consider an organism that is 2n=32.

Answer 1

Question-

Option A- INCORRECT STATEMENT

Reason-Sperm is the male gamete and egg/ova is the female gamete produced by sexually reproducing organisms. Both of these gametes are haploid 'n' and contains only half the no. of chromosomes. During the process of fertilization sperm and egg, fuse to form a diploid cell called the zygote. The zygote further develops into an embryo.

Option B-  CORRECT STATEMENT

Reason-Gametes are the reproductive cells produced by the sexually reproducing organisms. Sperm and egg both contain half the number of chromosomes due to the reductional division (meiosis). Each of these haploid gametes fuses to form a diploid cell having a complete set of homologous chromosome pair inherited from the mother and father.

Option C -INCORRECT STATEMENT

Reason- offspring from sexually reproducing organisms will have the same number of the chromosome as of the parental due to the reductional division(meiosis).

Option D- INCORRECT STATEMENT

Reason- Gametes are the reproductive cells of a sexually reproducing organism. They are haploid and contains only half the number of chromosome ( 23 pairs of chromosomes). During the process of fertilization, the male gamete (sperm) and the female gamete (egg) fuse to form a diploid cell having a total 46 pair of the chromosome called a zygote.

Hence option B is the correct statement.
