What is the probability of getting male and female offspring in human?
The male to female human sex ratio varies, due to demographics, environment, sex deterministic abortion, and imbalance in the male/female sperm viability ratio. The secondary ratio of boys to girls is about 105 to 100, or about 0.525 male. Estimates of the current birth sex ratio is about 0.535 male. The current global sex ratio (population) is about 0.507 male (2010) to 0.508 male (projected 2011).

What is the sex population distribution mean?

What is the ratio of women to men world wide?
As of recent estimates, the global sex ratio is approximately 101 men for every 100 women, meaning there are slightly more men than women worldwide. This translates to a ratio of about 49.5% women to 50.5% men. However, this ratio can vary by region and is influenced by factors such as birth rates, life expectancy, and social conditions.
What is the difference between statistical age standardisation and age-gender standardisation?
Whereas age-standardization adjusts for underlying differences in the age distribution of the combined male-female population, age/sex-standardized rates adjust for differences in the population distribution by both age and sex simultaneously.Age/sex-standardized rates are NOT the same as sex-specific age-adjusted rates.Like age, sex has a powerful influence on disease rates. Males and females have markedly different incidence, prevalence, and mortality rates for certain diseases and males have a shorter life expectancy than females.Therefore, in order to fully account for these differences, researchers may want to adjust for both age and sex when making comparisons for some conditions.The calculation for age/sex adjustment differs from age-standardization in that the individual age-specific rates are stratified by sex and are applied to the standard population stratified by sex.The requirements for the calculation of age/sex standardized rates are:Study population by age and sexStandard population by age and sexNumber of events for males and females in the study populationFormulaei(f) is the number of events for females in age group iei(m) is the number of events for males in age group ipi(f) is the number of females in age group i the study populationpi(m) is the number of males in age group i the study populationPi(f) is the number of females in age group i in the Standard populationPi(m) is the number of males in age group i in the Standard populationFor each age stratum the expected number of events is the sum of the expected number of events for males plus the expected number of events for females in that stratumAge-specific expected events= Ei=[(ei(m) /pi(m) ) *Pi(m) ] + [ (ei(f) /pi(f) ) *Pi(f) ]The age/sex Standardized Rate (per 100 000) is the sum of all expected events divided by the total standard population= [ Sum(Ei)/Sum(Pi)] * 1000

What is the ratio between boy or girl in the world?
Sex ratio denotes the ratio of males to females in a population. The primary sex ratio is the ratio at the time of conception, secondary sex ratio is the ratio at time of birth, and tertiary sex ratio is the ratio of adult human beings. According to CIA estimates the current world sex ratio at birth is 107 boys to 100 girls. In 2010 the global sex ratio was 986 females to 1000 males, which got further reduced to 984 females to 1000 males in 2011.
Why do you not need to consider the sex ratio for an ant population?
You do not need to consider the sex ratio for an ant population as the Queen ant creates all the eggs, which they hatch and become worker ants to feed the queen so the Queen can reproduce, if all the worker ants die, the Queen dies and no eggs are laid, so the sex ratio is not considered in an ant population.
How is sex ratio related to population size?
Sex ratio can be influenced by population size, as small populations may experience greater fluctuations in the ratio due to chance events. In larger populations, there is usually more stability in the sex ratio due to statistical laws of large numbers. Additionally, factors such as social structures and cultural preferences can also influence sex ratios in a population regardless of its size.
Causes of rapid population growth?
The answer to a rapid growth in population is in how many times people have sex each hour/day if people keep having sex then the population will grow more and more each day/week.
Is sex affect the growth when watching it at 15 years old?
I wouldn't say watching porn would affect physical growth, but mental growth. Mentally at the age of 15 a person is still learning about who they are sexually and what type of person they want to grow up to be. The constant viewing of sex will affect this mental growth and could affect future relationships.
