Nondisjunction results in cells with abnormal numbers of chromosomes due to chromosomes not separating properly in meiosis. this causes some cells to end up with to many chromosomes and others to end up with not enough chromosomes. It messes up cell division and development and can lead to death or genetic disorders like Down syndrome.

What is the relationship between dominant and recessive allelse?
Dominant alleles are those that express their traits even when only one copy is present, while recessive alleles require two copies to manifest their traits. In a heterozygous individual (one dominant and one recessive allele), the dominant allele will mask the effect of the recessive allele. This relationship is fundamental in genetics, influencing inheritance patterns and phenotypic traits in organisms.
Is it true that a defective allele always recessive and a normal allele always dominant?
No, a defective allele is not always recessive, and a normal allele is not always dominant. The relationship between alleles can be more complex and dependent on specific genetic mechanisms. Dominance and recessiveness are general terms used to describe the relationship between two alleles at a specific gene locus.
Is the difference between a dominant and recessive allele?
dominant-appears in first generation recessive-seems to dissapear
What are dominit and ressive?
It seems like there is a typo in your question. If you meant "dominant" and "recessive," they are terms used in genetics to describe the relationship between two versions of a gene. A dominant gene will be expressed over a recessive gene when present in an individual's genetic makeup.
What is the relation between dominant and recessive alleles?
the dominant trait is the stronger one and the recessive trait is the weaker one
Is co-dominant recessive?
No, codominance is a genetic relationship between two versions of a gene where both versions are expressed in the phenotype. In contrast, recessive traits are only expressed when an individual has two copies of the recessive allele.
Differences between dominant and recessive?
Dominant is stronger than recessive. So you can only have the phenotype ( visual characteristic ) of a recessive allele if you have 2 recessive alleles in your DNA , and other combination the dominant allele would be predominant
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
Is there a relationship between the frequency of a trait in a population and whether that trait is dominant or recessive?
Some observable traits in humans are dimples, earlobes, tongue-rolling, cleft chin, hairline, and freckles. The relationship between the frequency of a trait in a population and whether the trait is dominant or recessive because in inherited human traits, the offspring can either have dimples or no dimples.
What is the similarity between dominant and recessive?
la chee
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
