REQUIRED13.What is a good definition for non-disjunction?the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.the failure of homologous chromosomes or sister chromatids to separate normally during nuclear division, resulting in an abnormal distribution of chromosomes in the daughter nuclei.a change in the DNA sequence of an organism.a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

Non-disjunction can occur if __________ chromosomes fail to separate during meiosis I.Question 8Select one:a.homologousb.heterologousc.defectived.mutated

The type of genetic disorders mainly caused by chromosomal non-disjunction is

Nondisjunction of the ______ chromosome during meiosis can produce offspring that are XXX or XXY.

Refer to the figure above, what happened to the chromosomes that are labeled “nondisjunction”?Chromosomes are stuck to each other and do not move.Sister chromatids fail to separate/split and the entire chromosome move to one pole of the cell.Chromosomes stat to look like flowers Homologous paired chromosomes fail to separate/split and the entire chromosome move to one pole of the cell.

Nondisjunction might result in gametes with the chromosome numbers ________.2n + 1 or n - 1n + 1 or n - 12n + 1 or 2n - 1
