<em><u>Both </u></em><em><u>parents</u></em><em><u> </u></em><em><u>were </u></em><em><u>short</u></em><em><u>.</u></em>
this is because a recessive allele will only express itself in the absence of dominant allele
There are high risk of following abnormalities or mis- happening if chorionic villus sampling (CVS) are performed before 10th week of pregnancy:
a) Fetal defects
b) Miscarraige
c) Fetal anomalies.
d) Risk of infection
As per the standard recommended by American Congress of Obstetricians and Gynecologists, the standard time to perform this test is between 10th & 12th week as at that time the chances of risk to fetus is very negligible. In no case CVs shall be conducted before 9th week of gestation.
It is estimated that there is a risk of 0.5 to 1 % of miscarriage after CVs which usually happens within the 3rd day of test.

There were 100 new cases of syphilis last year in a given population of 100,000 people. At that time, 500 people in this population already had syphilis. The incidence of syphilis in this population is __________.
a. 100 per 100,000
b. 500 per 100,000
c. 1000 per 100,000
d. 5000 per 100,000
Answer:
a. 100 per 100,000
Explanation:
Incidence rate of a population can be defined as the rate at which an disease occurs in a population.
The incidence of a population is calculated as
The number of new cases ÷ The population of the people
From the above question,
The number of new cases = 100
The population of the people = 100,000
The incidence = 100 ÷ 100,000
The incidence of syphilis in the population is 100 per 100,000
