Males are considered hetero-gametic because they possess two different types of sex chromosomes: one X and one Y chromosome (XY configuration). In contrast, females have two of the same type of sex chromosome (XX configuration), making them homo-gametic. The presence of the Y chromosome in males determines male sex characteristics, while the X chromosome carries various genes that are essential for both sexes. Thus, the distinction in gametes—sperm carrying either an X or a Y chromosome—leads to the classification of males as hetero-gametic.

Why are human females homogametic?
Human females are homogametic because they have two X chromosomes (XX), making them the heterogametic sex, while males have one X and one Y chromosome (XY). This is in contrast to species where males are homogametic and females are heterogametic, such as birds.
What is a z chromosome?
A Z chromosome is a sex chromosome in a species in which the female is heterogametic (i.e. has different sex chromosomes). The counterpart is the W chromosome. In an XY system (e.g. humans), the male is heterogametic, XY, and the female is homogametic, XX. In a ZW system, the male is homogametic, ZZ, and the female is heterogametic, ZW. Examples of species with ZW systems include all birds, many reptiles, fishes and some insects.
Why male is called heterogametic?
Male is called heterogametic because they produce two different types of gametes (sperm), carrying either an X or a Y chromosome. In humans, males are XY, which means they determine the sex of the offspring. On the other hand, females are homogametic, as they produce only one type of gamete (eggs) carrying an X chromosome.
Do males or females snore worse?
Males
How many pairs of sex chromosomes do human have name them?
Humans have two sex chromosomes, the X and the Y. Human females have two X sex chromosomes and are said to be XX. Human males have one X and one Y chromosome and are said to be XY.
Why are human females homogametic?
Human females are homogametic because they have two X chromosomes (XX), making them the heterogametic sex, while males have one X and one Y chromosome (XY). This is in contrast to species where males are homogametic and females are heterogametic, such as birds.
Why human male is heterogametic and female is homogametic?
In mammals, including humans, males have one X and one Y chromosome (XY) while females have two X chromosomes (XX). The presence of the Y chromosome in males determines their heterogametic status, as the Y chromosome carries the SRY gene responsible for male development. In contrast, females do not have a Y chromosome, making them homogametic with two X chromosomes.
Female birds are heterogametic sex?
No.
What is a female peguin called?
I'm reasonably sure it's a hen, and males are cocks. (Don't snicker, even if you are a disgruntled female.) This is the correct nomenclature for game and domestic fowl, and I think it carries over to all birds. Otherwise, you could refer to them as "ZW penguins", after their heterogametic chromosome makeup (unlike most , but not all, species, in which the male is the heterogametic sex), or simply "the female". If the latter is good enough for David Attenborough, it's good enough for me.

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.

What is the only lizard that uses asexual reprodution?
Female Komodo dragons (the largest lizard) can produce offspring by parthenogenesis when no male is available for sexual reproduction. Their offspring are homozygous at every locus including having identical sex chromosomes. Thus the females produce all males because, unlike mammals, females are the heterogametic sex (ZW) while males are homogametic (ZZ).

Is said a male or female name?
"Said" is a gender-neutral Arabic name that can be used for both males and females.
Is it a boy are a girl cause they said she is gay?
The term "gay" may refer to males or females.
What percentage of Russians are said to drink tea?
It is estimated that about 82% of all Russians are said to drink tea as per a study done in 2005. This tea consumption is for both males and females and is said to be done daily.
