What are the secondary physical characteristics?
Secondary physical characteristics are physical traits that develop during puberty, such as facial hair in males, breast development in females, and changes in body shape. These characteristics are typically related to sexual maturation and differentiation between genders.
What are the visible signs of sexual maturity that do not involve the sex organs directly called?
Secondary sexual characteristics. These are physical manifestations that develop during puberty, such as breast development in females, facial hair growth in males, and changes in body shape and voice pitch. These traits are not directly related to the reproductive organs but are influenced by sex hormones and indicate sexual maturity.
What is the difference between primary and secondary sex characteristics?
Primary characteristics involve the organs for reproduction. Males have testicles, females uterus. Secondary characteristics involve traits characterized by hormonal changes such as the differences due to puberty. Examples include breasts, facial hair, the growth of pubic hair and underarm hair.
What is the similarities of sex-linked and sex influenced?
Both sex-linked and sex-influenced traits are influenced by the individual's sex. Sex-linked traits are determined by genes located on the sex chromosomes, while sex-influenced traits are influenced by sex hormones and may be expressed differently in males and females despite being on autosomes.
For what are genes on the y chromosome responsible?
Genes on the Y chromosome are responsible for male sex determination and other male-specific traits. They play a crucial role in the development of male reproductive organs and secondary sexual characteristics.
Why are these characteristics called secondary?
Secondary characteristics refer to traits that appear after puberty and are not directly related to reproduction. These traits are influenced by hormones and play a role in attracting mates or establishing social dominance. They are called secondary to distinguish them from primary sexual characteristics, which are directly involved in reproduction.
What are sex-limited traits and how do they manifest differently in males and females?
Sex-limited traits are characteristics that are only expressed in one sex due to differences in anatomy or physiology. These traits manifest differently in males and females because they are controlled by sex-specific hormones or genes. For example, male-pattern baldness is a sex-limited trait that is typically only seen in males due to the influence of male hormones like testosterone.
What is an example of a sex limited trait?
The traits which are influenced by the sex are called sex limited traits. These traits are just limited to one sex, either in male or female. For example, the genes for pattern baldness are present in both the sexes but expresses more in male as compare to female.
What are the secondary physical characteristics?
Secondary physical characteristics are physical traits that develop during puberty, such as facial hair in males, breast development in females, and changes in body shape. These characteristics are typically related to sexual maturation and differentiation between genders.
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for natural selection

How does sex differentiation occur in biological organisms?
Sex differentiation in biological organisms occurs through a combination of genetic and hormonal factors. The presence of specific sex chromosomes, such as XX for females and XY for males in humans, determines the individual's sex. Hormones, such as testosterone and estrogen, play a crucial role in the development of secondary sexual characteristics, such as reproductive organs and physical traits. During embryonic development, the expression of certain genes and the influence of hormones guide the differentiation of gonads into testes or ovaries, leading to the development of male or female characteristics.
Are genes are responsible for all the traits of an organism.?
no they are not.
What traits would you expect birds to have?
Males that are much larger than females.
