What is the genotype for males and females?
XX for female and XY for male. -anonymous18_K
What sex hormone is present in both males and females?
Testosterone is a sex hormone present in both males and females, although males typically have higher levels. In females, testosterone is produced in the ovaries and adrenal glands, and plays a role in maintaining bone density, muscle mass, and sex drive.
Chromosome pairs what and are distributed to sex cells?
Chromosome pairs undergo a process called meiosis during which they are divided. One of the pairs, known as the sex chromosomes, determines the sex of an individual. In humans, females have two X chromosomes, while males have one X and one Y chromosome. These sex chromosomes are distributed randomly to sex cells during meiosis, resulting in the formation of eggs (in females) and sperm (in males) with varying combinations of sex chromosomes.
How do you sex a common pleco?
To sex a common pleco, look for differences in body shape and fin structure. Males are typically more slender with larger, more pronounced pectoral fins that have a more pointed shape, while females are rounder and have smaller, more rounded fins. During breeding season, males may also develop bristle-like structures on their snouts, which females lack. Observing these physical characteristics can help determine the sex of the fish.
How many pairs of chromosomes do females have?
In humans, the somatic cells of both females and males have 23 chromosome pairs.

How is the sex of a crocodile determined?
The sex of a crocodile is typically determined by the temperature at which the eggs are incubated. In general, warmer temperatures during incubation result in more males, while cooler temperatures result in more females. This phenomenon is known as temperature-dependent sex determination.
What is a sex-limited trait and how does it manifest differently in males and females?
A sex-limited trait is a characteristic that is only expressed in one sex, either male or female. This trait is typically controlled by genes located on sex chromosomes. For example, male pattern baldness is a sex-limited trait that is more commonly seen in males than females. In this case, the trait manifests differently in males and females due to the influence of sex hormones and genetic factors specific to each sex.
What is the primary sex organ of females called?
A females primary sex organ is called an ovary.
Why do some females love to eat semen?
It's a psychological thing they love sex they love please their partner during sex and when the partner comes during oral sex they love that as well because it is a material indicator of their success.
What are the differences in reproductive strategies between the heterogametic sex and the homogametic sex in various species?
In many species, the heterogametic sex (typically males) produces different types of sex cells (sperm) while the homogametic sex (typically females) produces only one type of sex cell (egg). This difference in sex cell production leads to different reproductive strategies, with males typically producing many small, mobile sperm to increase the chances of fertilization, while females produce fewer, larger, and less mobile eggs. This difference in reproductive strategies is known as anisogamy.
How do you tell the sex of a Northern Sagebrush Lizard?
To determine the sex of a Northern Sagebrush Lizard, look for physical differences: males typically have brighter coloration, especially during the breeding season, and may exhibit a blue or greenish hue on their throats and bellies. Males also tend to have larger heads and more pronounced femoral pores compared to females. Additionally, females are generally larger overall and may display a more subdued coloration. Observing these characteristics during the lizard's active season can help identify their sex effectively.
What Gene difference between human males and females?
One of the key genetic differences between human males and females is the presence of sex chromosomes. Males typically have one X and one Y chromosome (XY), while females have two X chromosomes (XX). This difference in sex chromosomes leads to differences in the expression of certain genes related to sex determination and secondary sexual characteristics.
How many pairs of chromosomes do females have?
In humans, the somatic cells of both females and males have 23 chromosome pairs.
