The result is the zygote that contains 46 chromosomes 23 pairs of chromosomes. Humans have 23 pairs of chromosomes for a total of 46 chromosomes.

These numbers and the way that the DNA is made up is different for every species. Usually people have 23 pairs of chromosomes within their own bodies or equivalent to 46 copies. In fact each species of plants and animals has a set number of chromosomes.

Some carp and some ferns have more than 50 chromosomes in the haploid genome. How many chromosomes do Wisconsin Fast Plants have. A bacteria has 2 chromosomes A mosquito has 6 chromosomes A pea plant has 14 A sunflower has 34 A cat has 38 A puffer fish 42 A human being has 46 A dog has 78.

In fact each species of plants and animals has a set number of chromosomes. HUMANS usually have 46 chromosomes but 22 of those are copiesEach cell of the body contains a full set of chromosomes and humans could have as many. The DNA on a chromosome is like a thread of genes interspersed with other DNA that does other jobs such as regulating genes or its ancestral genetic material.

For example haplopappus has 4 chromosomes and. A fruit fly for example has four pairs of chromosomes while a rice plant has 12 and a dog 39. 215 rows As other non-human extant hominidae have 48 chromosomes it is believed that the human.

Each gene is a stretch of DNA that has the instructions for a specific protein. 21 23 and 24. But in plants and animals the number varies greatly.

While the exact number of chromosomes varies from species to species the number of chromosomes found within a species always remains the same. A fruit fly for example has four pairs of chromosomes while a rice plant has 12 and a dog 39. What this means is that the genes not the chromosomes matter in making a plant or animal what they are.

A plant cell have 24 chromosomes that have been proved in univen laboratory it is different in different plants. Every animal and plant cell has chromosomes. Each DNA set has two short arms.

One of each pair from either parent. 5 Chromosomes contain the DNA needed to create an animal or plant Credit. As you may have already guessed every animal and species has a set number of chromosomes this is even including plants.

Plants and animals have thousands or tens of thousands of genes scattered throughout their chromosomes. These thousands or tens of thousands of proteins all work together to make a working plant or animal. Triploid plants are sterile because chromosomes need to occur in pairs to produce viable offspring.
