they contain the same number of chromosome's :)

Can a sperm cell contain maternal chromosomes?
Absolutely (assuming you are referering to the maternal chromosomes of the man who is making the sperm) , the human set of chromosomes is composed of 46 pairs with half (23) coming from each parent. Mendel's laws suggest that each chromosome segregates and separates independently during mitosis (and subsequently meiosis) thus each gamete should contain a mixture of paternally and maternally derived chromosomes.
Girls suggest and boys command?
Every relationship is different, and every individual is different. Some girls suggest, some girls command, some boys suggest, and some boys command. Commanding, however, is not always the best way to get what you'd like, and can sometimes create resentment.
What is the change in chromosome number in meiosis?
The Reduction of Chromosome Number in Meiosis Is Determined by Properties Built into the Chromosomes. In meiosis I, two chromatids move to each spindle pole. Then, in meiosis II, the two are distributed, one to each future gamete. This requires that meiosis I chromosomes attach to the spindle differently than meiosis II chromosomes and that they regulate chromosome cohesion differently. We investigated whether the information that dictates the division type of the chromosome comes from the whole cell, the spindle, or the chromosome itself. Also, we determined when chromosomes can switch from meiosis I behavior to meiosis II behavior. We used a micromanipulation needle to fuse grasshopper spermatocytes in meiosis I to spermatocytes in meiosis II, and to move chromosomes from one spindle to the other. Chromosomes placed on spindles of a different meiotic division always behaved as they would have on their native spindle; e.g., a meiosis I chromosome attached to a meiosis II spindle in its normal fashion and sister chromatids moved together to the same spindle pole. We also showed that meiosis I chromosomes become competent meiosis II chromosomes in anaphase of meiosis I, but not before. The patterns for attachment to the spindle and regulation of cohesion are built into the chromosome itself. These results suggest that regulation of chromosome cohesion may be linked to differences in the arrangement of kinetochores in the two meiotic divisions.
Suggest a reason for the great variability seen in the structure of pollen grains?
because of the different types of flowers
Is it possible that some planets have life on them and suggest a reason why we are unlikely ever to visit these life forms.?
the planets containing life form other than earth may have a dangerous species, or the planet itself may be dangerous.
What might different sized eukaryote having chromosomes suggest about the size and organization of chromosomes in different species?
Identify the stages of these cells
Some species have the same chromosome number but they are different. Suggest an explanation?
Some species have same number of chromosomes but they are different. suggest an explanation
Some species have same number of chromosome but they are different .Suggest an explanation?
some species have same number of charosomes but they are different because Fusion is a common way for animal species to end up with a different number of chromosomes from their ancestors.
What Different types of Evidence used when comparing plant species?
Physiological similarities suggest the species evolved from the same ancestor.
What do common structures in two different species suggest?
They have a common ancestor they both might have evolved from.
Requirements that snakes have for their habitat?
It depends on the species entirely. Snakes have very different requirements from one another, I would suggest Googling care of a specific species for a better answer.
Why is there a 50 and 50 percent probability to have a boy or girl in pregnancy?
It is like tossing a coin. Heads or tails. There are usually only 2 choices.That said an animal's sex is often determined by the sex chromosomes it inherits. The new research reveals that species with X and Y sex chromosomes, including mammals, generally have female-skewed populations.Species where males are the sex that has different sex chromosomes are significantly female-biased,with adult sex ratios slanting more than 56 percent female. The human male has a Y chromosome that is much different than the female X.Researchers suggest whichever sex has two different sex chromosomes may suffer a higher rate of mortality after birth.
Would it be illegal to collect money to haiti unauthorized?
of course not. that's like saying, if you have a pet panda and you want to save the panda species, is it illegal? no, they need your help. though i suggest contacting an organization.

What couler are ameba?
I assume that you are asking what color amoeba are? The answer: They most likely vary by species. There many different species of amoeba. Stereotypically, in cartoons or illustrations, they are green. I would suggest using Google images to quell your curiosity.
What is the most important resource in an organization?
I am curious about the answer. I will suggest the answer is human resources.
How does comparing physiological similarities of living species provide evidence of?
Physiological similarities suggest the species evolved from the same ancestor.
