Answer:

The offspring of organisms that is reproduce through sexually are not genetically identical to their parents because the offspring contains genes from two parents.

Explanation:

Identical offspring is only formed when offspring is produced from one parent through asexual reproduction such as building, binary fission and fragmentation. In sexual reproduction, offspring is produced by the mating of two organisms i. e. male and female organism. That's why genes of offspring are different from their parents and offspring is not identical to parents.

Answer: offspring of organisms that reproduce sexually are not genetically identical to their parents because the offsprings inherited half of their total DNA from each parent.

Explanation: During sexual reproduction, offsprings are produced by a combination of genetic material from both parents. Each parent contributes half of the offspring's total DNA because during fertilization, a sperm cell from the father fuses with an egg from the mother to form a zygote which develops into an offspring.

A genetical identical offspring can only be produced from one parent through asexual means in which the offsprings inherits all of its total DNA from one parent and looks exactly like the parent. But in sexual reproduction, offsprings are not genetically identical to the parents because the offsprings are a combination of the genetic material from both parents.

Aliens from the planet Zorg have 100 chromosomes in their diploid cells. If a diploid alien cell enters meiosis, how many chromo

stepan [7]

Answer:

Chromosomes at the conclusion of Meiosis I - $50$

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells

Explanation:

Given

Number of chromosomes in the diploid cells of Aliens from the planet Zorg $= 100$

In the Meiosis I cell division , a cell divides to produce two diploid cells with exactly the same amount of DNA as that of original parent cell.

However, the number of chromosomes is reduced to by half at the end of meiosis I

After Meiosis II, four haploid cells are produces with half the amount of DNA as that of original parent cell

Thus,

Chromosomes at the conclusion of Meiosis I - $50$

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
