What are the factors that determine the sex of an individual?
In humans, biological sex is determined by five factors present at birth: chromosomes, gonads, hormones, internal reproductive anatomy, and external genitalia. Sex is typically divided into male, female, or intersex (i.e., having some combination of both male and female sex characteristics).
What is the genotype of a biological female?
Using the definition of “genotype” that refers to a relevant section of the DNA sequence inherited by an organism, the genotype of female humans is XX, as opposed to male humans’ genotype XY.
How can a genotype be determined?
Genotype is determined by the makeup of alleles, pairs of genes responsible for particular traits. An allele can be made up of two dominant genes, a dominant and a recessive gene, or two recessive genes. The combination of the two, and which one is dominant, determines what trait the allele will express.
How do chromosomes determine gender?
Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes: Females have 2 X chromosomes. Males have 1 X and 1 Y chromosome.
Is gender a phenotype or genotype?
Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male). Phenotypic sex refers to an individual’s sex as determined by their internal and external genitalia, expression of secondary sex characteristics, and behavior.
How do you think sex is determined in a person with a chromosomal disorder involving the sex chromosomes?
Sex chromosome abnormalities are gender specific. Normal males inherit an X and a Y chromosome while females have two X’s. A single Y chromosome is sufficient to produce maleness while its absence is necessary for femaleness. Female abnormalities are due to variations in the number of X chromosomes.
What is genotype phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What genotype must a woman have?
Females will have two X-linked alleles (because females are XX), whereas males will only have one X-linked allele (because males are XY).
What are the two types of chromosomes that determine gender?
Sex Chromosome. A sex chromosome is a type of chromosome that participates in sex determination. Humans and most other mammals have two sex chromosomes, the X and the Y. Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells.
If sex is a biological concept, then gender is a social concept. It refers to the social and cultural differences a society assigns to people based on their (biological) sex.
How do you determine the phenotype of an individual?
The phenotype is determined by an individual’s genotype and expressed genes or by visible trait, for instance, hair colour or type, eye colour body shape, and height. It depends on the genotype but also influenced by the factors in the environment.
What is sex and how is it determined?
Sex refers to the anatomical and other biological differences between females and males that are determined at the moment of conception and develop in the womb and throughout childhood and adolescence. Females, of course, have two X chromosomes, while males have one X chromosome and one Y chromosome.
