Summary Introduction
To determine:
The reason behind the increased level of FSH that raises the likelihood of fraternal twins.
Introduction:
The FSH (Follicle Stimulating Hormone) is released by the gonadotropic cells of anterior pituitary gland. FSH helps in the regulation of sexual development, pubertal maturation, growth, and reproductive processes in an individual. FSH plays an important role in the maturation of germ cells, initiate follicular growth and induces ovary to produce estrogen.

- Define external fertilisation. Mention its disadvantages.arrow_forward_____ is a form of 46,XY intersex that affects chromosomal males. It is by far the most common form of 46,XY intersex. These individuals have testes that produce testosterone, but their bodies lack working androgen receptors. When these individuals are born they often have female-typical genitalia, and they develop female secondary sex characteristics at puberty. They also tend to develop a female gender identity.

- The development of sex and gender is a good example of a developmental cascade because: Group of answer choices Although having an X and a Y chromosome at conception typically leads to the development of testes during prenatal development, this may not lead to typical male genitalia if certain hormones are present later in development Two people may have the same gonads early in prenatal development but end up with different external genitalia and gender identities as a result of differences in the prenatal environment All of the options listed here are correct Having two X chromosomes at conception typically leads to the development of ovaries during prenatal development, which typically leads to high levels of estrogen in puberty, which typically leads to a female gender identity in adulthoodarrow_forwardData:Total Births: 2,700 Low Birth Weight: 264Mothers with inter-gestational interval < 12 months: 92Mothers with low birth weight with inter-gestational interval < 12 months: 21Mothers with previous HTN: 18Mothers with low birth weight with previous HT: 15 A) Global or absolute risk of low birth weight.B) Relative risk for the factor "inter-gestational interval < 12 months". According to the results obtained, give your opinion as to whether there is an association or not and express it accordingly.C) Relative risk for the factor "mothers with previous HTN". According to the results obtained, give your opinion as to whether or not there is an association and express it accordingly.D) In the case of the factors in which you consider, according to the results obtained, that there is an association, calculate the Attributable Risk (AR) and the Etiological Risk Fraction (ERF), expressing in both cases their significance.arrow_forwardQ1: What is the probability that a child with one parent who has an autosomal dominant disorder will inherit the disease? Q2: Why are there no carriers with a dominant genetic disorder? Q3: Because dominant genetic disorders are rare, it is extremely rare for both parents to have the condition (genotype Aa). Draw a Punnett square with two Aa parents. What proportion of the offspring would have the disorder? What proportion would be normal?arrow_forward
