What happens if a human has 45 chromosomes?
Turner syndrome is due to a chromosomal abnormality in which all or part of one of the X chromosomes is missing or altered. While most people have 46 chromosomes, people with TS usually have 45. The chromosomal abnormality may be present in just some cells in which case it is known as TS with mosaicism.
Are real bananas extinct?
Bananas are the world’s most popular fruit, but the banana industry is currently dominated by one type of banana: the Cavendish (or supermarket banana) that we all know and love. The Cavendish banana rose to fame in 1965 when the previous banana superstar, the Gros Michel, officially became extinct and lost the throne.

Pears originated in southeastern Europe and were a favorite food of the ancient Greeks and Romans. The ancient Greek author Homer described them as “gifts from the gods” likely due to their sweet, juicy flavor. The early Romans developed 50 varieties of pear and planted them across Europe.
How many pairs of chromosomes are in a human cell?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
How many X chromosomes do males and females have?
The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size.
How many chromosomes does a Drosophila melanogaster have?
Drosophila Chromosomes: In Drosophila melanogaster there are 4 homologous pairs of chromosomes: 2 pairs of large autosomes, (one slightly smaller than the other pair), 1 pair of very small autosomes, and a pair of sex chromosomes. Females normally have two X chromosomes; males have one X and one tiny Y chromosome. Click to see full answer.
What foods have the same chromosome number as broccoli?

How many chromosomes does the modern apple have?
The modern apple has 17 chromosomes which were found to be derived from an ancestor with 9 chromosomes that experienced genome-wide duplication. The genome sequence also provided proof that Malus sieversii was the wild ancestor of the domestic apple—an issue that had been long-debated in the scientific community.
How many genes are in the apple genome?
The apple genome has approximately 57,000 genes, which was the highest number of any plant genome studied at the time, and more genes than the human genome which has about 25,000 genes. 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 does a triploid apple tree have?
However several important apple varieties have three sets of chromosomes rather than two, and are known as triploids. Triploid apple varieties have a couple of important characteristics which need to be considered when growing them: Their pollen is effectively sterile and cannot be used to pollinate other apple trees.
