WebNondisjunction in meiosis II=out of 4 gametes formed, one will be (n+1), other will be (n-1) and the other 2 will be n (normal). Fusion of n+1 gamete with normal gamete (n)= 2n+1 or trisomic Fusion of n-1 gamete with normal gamete (n)=2n-1 or monosomic Fusion of n gamete with normal gamete (n)=2n (normal diploid) WebMar 1, 2024 · If the latter combined with a haploid gamete, the result would be a trisomic zygote leading to a triploid cell line as observed for F. cylindrus CCMP1102 with three copies in two distinct haplotypes, each parental line and a recombinant. Polyploidy is a significant driving force in the evolution of diatom species (Parks et al., 2024).
WebA gamete that contains a chromosome with the normal gene arrangement. This gamete will produce offspring with the normal gene arrangement. A gamete that contains an inversion chromosome. Thus, inversion chromosomes are passed from parents to offspring. The resulting offspring will suffer no negative phenotypic effects. WebAccording to the law of segregation, only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random. When an egg and a sperm join in fertilization, they form a new …
WebJan 8, 2024 · However, few studies consider the possible contribution of aneuploidy that exists premeiotically in the human female. The origin of this type of aneuploidy occurs either in the primordial germ cells themselves, a proportion of which may be trisomic or monosomic (gonadal mosaicism) or during the extensive premeiotic mitotic divisions of … WebApr 14, 2024 · We report on the case of prenatal detection of trisomy 2 in placental biopsy and further algorithm of genetic counseling and testing.

Web3. (1 point) Nondisjunction can result in gametes that carry an extra copy of a chromosome, and at fertilization this can result in a zygote with a trisomy. In some cases, the zygote somehow eliminates one of the three copies of the trisomic chromosome, restoring euploidy. It's really not understood how this happens.
