Sex-linked Disorders

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Nondisjunction

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Nondisjunction

Nondisjunction

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...

Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Reproductive Cloning

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic cell—any cell that is not a sex...

Area of Science:

Perinatal Psychology
Neonatal Care
Family Studies

Context:

Examines paternal representations following disruptive births.
Considers diverse parental experiences in medicalized births with unavoidable separation.
Includes 50 families categorized by neonatal characteristics (e.g., premature birth, artificial insemination).

Purpose:

To explore the evolution of father representations after disruptive births.
To understand the father's role and support in the maternal psyche during the perinatal period.
To introduce an additional clinical perspective beyond the child's somatic state in mother-child relationship evolution.

Summary:

This study analyzes fathers' experiences and evolving representations after disruptive births.
It highlights the father's potential to support the maternal psyche when adequately assisted.
Data collected from 1990-1994 at Amiens Main Hospital and in families' homes.

Impact:

Offers insights into paternal roles in neonatal care and perinatal mental health.
Enriches clinical understanding by incorporating paternal representations in mother-child relationship dynamics.
Underscores the importance of supporting fathers for improved family well-being post-disruptive birth.
