When two grasshopper sex cells join, the chromosome number in the new cell is (half/double) the number in the sex cells. The grasshopper number of chromosomes in the new cell are diploid (double) because it get haploid number of chromosomes (n=12) from each parent.

The karyotype is consisting of 2n = 23 in males and 2n = 24 in females with autosomal fundamental number of 22. All the autosomal chromosomes are telocentric and the X chromo some is acrocentric, having a small second arm (Fig.

six chromosomes

The six chromosomes represent two three-chromosome sets; the mosquito received one set of three chromosomes from the egg cell of the mother and a similar set of three chromosomes from the sperm cell of the father. The only exception to the six chromosomes per cell rule for mosquitoes would be the gametes, or sex cells.

The organism with the highest chromosome number recorded in to date is estimated to be 1,440 (or 720 pairs) found in the adder’s tongue fern Ophioglossum reticulatum. Original text presents information as: “to date is 2n = ca.

In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.

Humans are not the only animal with 23 pairs, either–the Chinese subspecies of Muntiacusmuntjac, a small kind of deer, also has 23 pairs of chromosomes. Are you ready for something really weird, though? A different subspecies of this same deer has only three pairs!

Sable antelope have 46 just like humans but they would not be able to have offspring with humans. They do not match up.

Could we mate with other animals today? Probably not. Ethical considerations preclude definitive research on the subject, but it’s safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.

In a remarkable—if likely controversial—feat, scientists announced today that they have created the first successful human-animal hybrids. The project proves that human cells can be introduced into a non-human organism, survive, and even grow inside a host animal, in this case, pigs.

But creating hybrids of animals that are very genetically distinct from each other – such as a dog and a cat – are impossible, as is one species giving birth to an entirely different one. It does not stop people from hoping.

Well, the short answer is no. Both animals and plants have evolved extensive mechanisms which prevent this from happening. First, sperm have to find their way to an egg.

You’re right, humans and dogs can’t reproduce. So you won’t get anything like Barf the Mog from Spaceballs. A half man/half dog wouldn’t get very far past a single cell (assuming the egg and sperm could even come together!). This is because dogs and people have very different sets of instructions in their DNA.

If you define crying as expressing emotion, such as grief or joy, then the answer is yes. Animals do create tears, but only to lubricate their eyes, says Bryan Amaral, senior curator of the Smithsonian’s National Zoo. Animals do feel emotions, too, but in nature it’s often to their advantage to mask them.

Sperm don’t have eyes. Sperm cells travel to the egg by moving their tail back and forth in a swimming motion. Sperm find the egg because there is a chemical around the egg that attracts the sperm and signals that the egg is ready.
