The complete linkage present only in male drosophila for a few reasons. One is that it is a sex-linked trait.
In Drosophila, male flies have only one X chromosome, so any gene located on the X chromosome will exhibit complete linkage in males because there is no second X chromosome to allow for recombination. Females have two X chromosomes, which can undergo crossing over during meiosis, leading to recombination of genes.
One pair of chromosomes constitute a single linkage group in humans except in case of sex chromosomes of male. In human females total of 23 linkage groups are present - 22 pair of autosomes and 1 pair of sex chromosomes (XX). In human male total of 24 linkage groups are present - 22 pair of autosomes , one X and one Y.
Gladiolus is a complete flower. The flowers have both male and female parts. There are no separate flowers for male and female. There are no separate male and female plants for gladiolus.
Canna is a complete flower. The flower has both male and female sex organs. You do not need to buy both a "male" plant and "female" plant.
The male reproductive gland that is present in humans but missing in cats is the bulbourethral gland (also known as Cowper's gland).

That the gene for white eyes was sex linked and on the y chromosome.
male
Drosophila males typically have larger bodies, darker pigmentation, and sex combs on their front legs, while females are usually smaller, lighter in color, and lack sex combs. Additionally, males have a rounder abdomen and a more pointed genitalia, while females have a more pointed abdomen and a wider genitalia.
Hydrangea have complete flowers. They do not have separate male and female flowers. They do not have separate male and female plants.
Gladiolus is a complete flower. The flowers have both male and female parts. There are no separate flowers for male and female. There are no separate male and female plants for gladiolus.
YES
At present there are far more male carpenters than female.
No, a male cannot have a vagina. A vagina is a female reproductive organ that is not present in males.
A male present in the body of a female is known as microchimerism. This occurs when a small number of cells or DNA from a male fetus or male donor persist in a female's body. This phenomenon can happen during pregnancy, organ transplantation, or blood transfusions.
Canna is a complete flower. The flower has both male and female sex organs. You do not need to buy both a "male" plant and "female" plant.
