The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.
By binding to DNA it triggers the transcription of a specific gene.
Nondisjunction is the the failure of homologous chromosomes of chromatids to segregate during meiosis or mitosis. Nondisjunction can result in cancer. Nondisjunction during meiosis results in one daughter cell having both a pair of parental chromosomes with the other having none. It causes mutation in the number of chromosomes, either extra chromosomes or missing chromosomes. Nondisjunction during meiosis can cause chromosomal disorders such as trisomy 21 (down Syndrome), Turner's Syndrome, and Klinefelter's Syndrome.
