how many pairs of chromosomes do bananas have?
316117
Banana varieties that are hybrids with AAB and ABB genome constitutions are a staple food for a billion people in Asia and Africa and have 2n=3x=33 chromosomes (Figure 1). About 15% of the world's banana production is for the export trade, and is based on a single variety, 'Cavendish'.

Human / Ape chromosome differences. Humans have a characteristic diploid chromosome number of 2N=46 whereas the other Great Apes (orangutans, gorillas, and chimps) are all 2N=48.

(The gametes of diploid organisms contain only single unpaired chromosomes and are called haploid.) Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs.

Chromosomes come in matching pairs, one pair from each parent. Humans, for example, have a total of 46 chromosomes, 23 from the mother and another 23 from the father. With two sets of chromosomes, children inherit two copies of each gene, one from each parent.

The modern apple has 17 chromosomes which were found to be derived from an ancestor with 9 chromosomes that experienced genome-wide duplication.

How many chromosomes do humans have? 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.

While great apes all have 48 chromosomes (24 pairs), humans have only 46 (23 pairs).

Answer and Explanation: Gorillas have 24 pairs of chromosomes, for a total of 48. This is same number of chromosomes that chimpanzees and orangutans have as well. In fact,...

There's something fascinating about our chromosomes. We have 23 pairs. Chimpanzees and gorillas, our closest living relatives, have 24.

For example, humans are diploid (2n) and have 46 chromosomes in their normal body cells. These 46 chromosomes are organized into 23 pairs: 22 pairs of autosomes and 1 pair of sex chromosomes. The sex cells of a human are haploid (n), containing only one homologous chromosome from each pair.

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs.

Almost every cell in our body contains 23 pairs of chromosomes, for a total of 46 chromosomes. Half of the chromosomes come from our mother, and the other half come from our father. The first 22 pairs are called autosomes.

And there is a wide range of chromosome numbers. Animal chromosome numbers range from 254 in hermit crabs to 2 in a species of roundworm. The fern called Ophioglossum reticulatum has 1260 chromosomes! Humans have 46, chimpanzees have 48, and yes, potatoes also have 48.

Mosquitoes, for example have a diploid chromosome number of six, frogs have 26 and shrimp have a whopping 508 chromosomes! But why do humans have 23 pairs?

It has only four pairs of chromosomes – three autosomes, and one pair of sex chromosomes. Males do not show meiotic recombination, facilitating genetic studies.
