How do you summarize the inheritance of sex-linked traits through meiosis ?
There is a resemblance between the separation of homologous chromosomes during anaphase I of meiosis and the postulated separation of character differences at the time of gamete formation. If each pair of homologous chromosomes is so oriented at metaphase I, so that in a pair the orientation of maternal and paternal chromosomes towards specific poles is independent of the orientation of these chromosomes in the pair.
In order to understand the inheritance of the characters present on the sex chromosomes, let us consider the transmission of the X- chromosomes from the male individual in man. The X-chromosomes from male individual will always, go to the daughter, while the X-chromosomes from the female individual will be distributed amongst both daughters and sons. Consequently, if the female parent carries the recessive character in homozygous condition and the male parent carries the dominant allele, the female individuals in the F1 generation will show the dominant phenotype, and the male individuals will show only recessive phenotype in this generation(F1). If inter crossing is now allowed among individuals from F1 generation, it is realized that the inheritance with respect to sex is of a criscross type.
