SEX CHROMOSOME , SEX DETERMINATION Flashcards
is an individual’s complete set of chromosomes.
KAROTYPE
Is a type of chromosome involved in sex determination.
SEX CHROMOSOME
Humans and most other mammals have how many sex chromosomes?
TWO
females have how many chromosomes?
two X chromosomes
males have how many chromosomes?
one X chromosome and one Y chromosome
The sex of an individual is determined by the ___________________contributed to the zygote by the sperm and the egg.
sex chromosomes
These are the female sex cells
egg cells
male gametes
sperm cells
process involved in which sperm and egg cell unites to form a zygote
fertilization
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
chromosome
humans have how many chromosomes?
46, 23 pairs of chromosomes
first 22 pairs are called
AUTOSOMES
carries the genetic coding for everything except sex determination
AUTOSOMES
last pair of chromosomes are called
SEX CHROMOSOMES
are numbered chromosomes that contain genes for anything that does not relate to sex determination
AUTOSOMES
is a type of chromosome involved in sex determination
SEX CHROMOSOMES
What type of cell division is responsible for the production of our gametes or sex cells?
MEIOSIS
is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.
MEIOSIS
when an egg is fertilized by a sperm with a Y chromosome, the offspring is?
MALE
when an egg is fertilized by a sperm with a X chromosome, the offspring is?
FEMALE
sex is determined by ?
FATHER
is a condition in which individuals with XY chromosomes have a genetic mutation that makes their bodies insensitive to androgens (male sex hormones). As a result, they may develop external female genitalia and often identify as females, despite having XY chromosomes.
ANDROGEN INSENSITIVITY SYNDROME
are a pair of chromosomes that determine an individual’s biological sex. In humans, there are two types of sex chromosomes: X and Y. Females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
SEX CHROMOSOMES
An individual’s biological sex is determined by the
