Abnormal chromosomal arrangements in human oocytes [PDF]

, 2017
Ninety-one human oocytes, lacking signs of fertilization 50 h after insemination in vitro, were investigated cytogenetically to assess the frequency and type of chromosomal abnormalities. Chromosome spreading permitted adequate karyotyping in 55 oocytes.

Sequencing the CHO DXB11 genome reveals regional variations in genomic stability and haploidy

BMC Genomics, 2015
BackgroundThe DHFR negative CHO DXB11 cell line (also known as DUX-B11 and DUKX) was historically the first CHO cell line to be used for large scale production of heterologous proteins and is still used for production of a number of complex proteins ...

The Constrained Maximal Expression Level Owing to Haploidy Shapes Gene Content on the Mammalian X Chromosome.

PLoS Biology, 2015
X chromosomes are unusual in many regards, not least of which is their nonrandom gene content. The causes of this bias are commonly discussed in the context of sexual antagonism and the avoidance of activity in the male germline.

Induced Gynogenesis in the Indian Major Carp, Cirrhinus mrigala (Ham.) [PDF]

, 1988
Artificial production of gynogenetic Cirrhinus mrigala (mrigal ) is reported for the first time. Ultraviolet irradiated Cyprinus carpio (common carp) milt was used for activating mrigal eggs.

Overexpression of Let-7a mitigates diploidization in mouse androgenetic haploid embryonic stem cells

iScience
Summary: Mouse androgenetic haploid embryonic stem cells (mAG-haESCs) can be utilized to uncover gene functions, especially those of genes with recessive effects, and to produce semicloned mice when injected into mature oocytes.
