Microscopic examination of a cell's chromosomes can reveal the sex of the fetus.───用显微镜检查细胞染色体可以查出胎儿的性别。
Karyotype reveal that in most cells all but sex chromosomes are present as two copies, referred to as homologous pairs.───除了性染色体外，大多数细胞的染色体组成对出现，称同源染色体对。
The only biological certainty is that the differing sex chromosomes almost invariably result in differing reproductive kit and body shape.───生物学唯一肯定的是，性染色体的不同似乎总会导致生殖系统和体形上的不同。
In diploid cells, there is a pair of sex chromosomes; the remainder are termed autosomes .───在二倍体细胞中，有一对性染色体，其余的都是常染色体。
Failure of the butterfly's sex chromosomes to separate during fertilisation is behind this rare sexual chimera.───在受精过程中蝴蝶的性染色体没有分离，这是这种性合体的原因。
This works for diploid plants, but numerous plant species are polyploid and must therefore have multiple sex chromosomes.───这对二倍体植物起作用，但多数植物是多倍体，它们必定有多条性染色体。
But sometimes a person has an abnormal number of sex chromosomes, which can result in various disorders that range in severity.───但有一些人的性染色体数量发生异常，按异常的严重程度可分类不同的类型。
Heterogametic sex The sex with dissimilar sex chromosomes, one (in mammals the Y chromosome)being shorter than the other(the X chromosome).
Homogametic sex The sex with homologous sex chromosomes, in mammals, designated XX.
From the cytogenetic perspective, only a small proportion of fish species have heteromorphic sex chromosomes.
All autosomes and sex chromosomes are measured and analysed according to relative length, arm ratio and centromere index of each chromosome including all the microchromosomes.
They diagnosed Klinefelter's syndrome, which means I have three sex chromosomes, XXY, instead of the normal XY for a male, or XX for a female.
NO dimorphic sex chromosomes were observed in either sexof the three species examined.
Humans have 22 chromosome pairs plus two sex chromosomes.
