Edwards syndrome, also known as trisomy 18, is typically caused by a random error in cell division that results in an extra chromosome 18. This chromosomal abnormality can occur in either the mother or father, but it is more commonly associated with maternal age, as older mothers have a higher risk of chromosomal abnormalities during egg formation. Neither parent "carries" the syndrome in a hereditary sense, as it is usually not inherited but rather occurs as a sporadic event during conception.
After the mother sea horse lays her eggs she gives them to the father to carry them around.
Yes, it is possible for both mother and father to be RH positive and a child to be RH negative.
A non-repeat mother without fragile X syndrome cannot pass the condition to her male offspring. Fragile X syndrome is caused by mutations in the FMR1 gene, specifically the expansion of CGG repeats, which typically occurs in carriers with a certain number of repeats. Since the mother does not have the syndrome or carry the premutation, her male offspring would not inherit the genetic mutation associated with fragile X syndrome.
The father and the mother give their baby one year of protection. During this year the father and mother teach their newborn how to hunt and look for shelter. After one year the father and the mother split and let their young to start their own life.
Both your mother's and father's DNA strands are transcribed to produce messenger RNA (mRNA) during gene expression. This mRNA is then translated into proteins that carry out various functions in the body.
You are the result of combination of chromosomes of your mother and father. That is why you are so much beautiful. Half the chromosomes come from father and half the chromosomes come from the mother.
No because her father and mother both did not have it, therefore it is impossible for her to have it
Down syndrome is an abnormality of the chromosomes and not genic in origin .This occurs in one of every two thousand newborns. People do not "carry" this and the child is born with three rather than two chromosomes numbered 21. The mother and father of the child are normal except in the rare case of a woman with Down syndrome who gives birth to a child; the copying or replication error occurs either in the germ cell or in the initial cell division of the embryo.
Probably brown. It depends on what the parents carry as a recessive gene.
For herself, it can affect the percentage of extras she's obligated to carry.
chromosome 21
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
