Sex-linked recessive
Autosomal recessive
Autosomal dominant
Sex-linked dominant –

one Y, if the affected chromosome has the illness, it will be expressed.

Mental illness
Check My Answer –
correct answers ✅Intellectual disability and fetal miscarriage. Chromosome
abnormalities are the leading known cause of intellectual disability and fetal

What are three examples of prenatal diagnostic studies?
Drug-sensitivity testing
Chorionic villus sampling (CVS)
Microscopy of cervical mucosa
Preimplantation genetic testing (PGT)
Amniocentesis –
correct answers ✅Chorionic villus sampling (CVS), amniocentesis, and
preimplantation genetic testing (PGT) are examples of prenatal diagnostic
studies and are performed in vitro. CVS is a form of genetic testing that
provides genetic information found in utero and is usually performed
between weeks 11 and 14 of pregnancy. An amniocentesis is a form of
genetic testing that evaluates amniotic fluid and is usually performed during
the second trimester, between weeks 15 and 20 of pregnancy. PGT is

How can an X-linked recessive disease skip generations?
Mothers cannot pass X-linked genes to their sons.
Females are homozygous for the X chromosome.
The disease can be transmitted through female carriers.
These diseases need only one copy of the gene in females. –
