“procreation”
“breeding”
.
(“reproduction” is the biological process by which new individual organisms – “offspring” – are produced from their “parents”)
.
(‘reproduction’ is a fundamental feature of all known ‘life’)
(each individual ‘organism’ exists as the result of ‘reproduction’)
(there are 2 forms of ‘reproduction’: ‘asexual’ and ‘sexual’)
(in ‘asexual reproduction’, an ‘organism’ can ‘reproduce’ without the ‘involvement’ of another ‘organism’)
(‘asexual reproduction’ is not limited to ‘single-celled organisms’)
(the cloning of an organism is a form of ‘asexual reproduction’)
(by ‘asexual reproduction’, an organism creates a genetically similar or identical copy of itself)
(the ‘evolution’ of ‘sexual reproduction’ is a ‘major puzzle’ for ‘biologists’)
(the 2-fold cost of ‘sexual reproduction’ is that only 50% of organisms reproduce and organisms only pass on 50% of their genes)
(‘sexual reproduction’ typically requires the sexual interaction of two specialized organisms, called ‘gametes’, which contain half the number of chromosomes of normal cells and are created by ‘meiosis’, with typically a male fertilizing a female of the same speciesto create a fertilized ‘zygote’)
,
(this produces offspring organisms whose genetic characteristics are derived from those of the 2 ‘parental organisms’)
.
The most fertile period (the time with the highest likelihood of pregnancy resulting from sexual intercourse) covers the time from some 5 days before until 1–2 days after ovulation.[30]
In a 28 day cycle with a 14-day luteal phase, this corresponds to the second and the beginning of the third week.
A variety of methods have been developed to help individual women estimate the relatively fertile and the relatively infertile days in the cycle:
these systems are called fertility awareness.
Fertility awareness methods that rely on cycle length records alone are called calendar-based methods.[31]
Methods that require observation of one or more of the three primary fertility signs (basal body temperature, cervical mucus, and cervical position)[32] are known as symptoms-based methods.[31]
Urine test kits are available that detect the LH surge that occurs 24 to 36 hours before ovulation;
these are known as ovulation predictor kits (OPKs).[33]
Computerized devices that interpret basal body temperatures, urinary test results, or changes in saliva are called fertility monitors.
A woman’s fertility is also affected by her age.[34]
As a woman’s total egg supply is formed in fetal life,[35] to be ovulated decades later, it has been suggested that this long lifetime may make the chromatin of eggs more vulnerable to division problems, breakage, and mutation than the chromatin of sperm, which are produced continuously during a man’s reproductive life.
However, despite this hypothesis, a similar paternal age effect has also been observed
