Diploid cells contain two copies of each chromosome. Why are there two copies of each?

Because one copy will be kept in the nucleus and one copy will be used in the cytoplasm.

Because the DNA is a double-helix.

Because each parent contributes one copy of their offspring.

Because the chromosomes are duplicated in case one gets damaged.

Answer #1

Answer: Because each parent contributes one copy of their offspring.

The diploid cells have 2 sets of a chromosome that means they have two copies of each chromosome. Diploid cells form from the fusion of haploid cells, that have a single set of chromosomes. Formation of a new diploid cell takes place when the gametes that are haploid cells from two different parent are fused to form a diploid structure which is known as zygote which later forms an individual with diploid cells and since two halpoid cells from different parents are fusing the diploid cell of newly formed individual of will have two set of chromosomes which are contributed by each parent.

6. Red-green color blindness occurs in about 8% of males and .4% of females. Many genes contribute to Red-green colorblindness and most of these are sex-linked, which is the reason for the disparity in the frequency between males and females. Call the allele that encodes a functional product "+" and the allele that encodes a non-functional product "=". Why is Red-green color blindness more fequent in males? a.   because males inherit only a single X chromosome, which means that inheriting...
