How many pairs of chromosomes do each parent contribute to the fertilized egg?
Each parent donates 23 chromosomes to his/her child.....23 chromosomes from mother and 23 chromosomes from father makes a total of 46 chromosomes a healthy child.
Is trisomy 13 inherited by a dominant or recessive trait or is it sex linked?
Trisomy 18 is a form of chromosomal aberration. It is neither recessive nor dominant. Neither does it show co-dominance or incomplete dominance factor. It arises due to the presence of an extra chromosome 18 in the somatic cells.
Does pollination occur when pollen combines with an egg?
Pollination is when the pollen grain lands on the stigma. It then grows a pollen tube and part of it, the actual male gamete, travels down and fuses with the ovule (egg) which is the actual fertilization.
A substance that combines with hydrogen ions?
A base
Energy is released when oxygen combines with?
glucose
What protein containing iron in red blood cells that combines with and transports O2?
Hemoglobin is the iron containing protein in our red blood cells that combines with and carries oxygen.
What do you call the single cell when a sperm's DNA combines with the egg's DNA?
the single cell when a sperm's DNA combines with the egg's DNA is called fertilization
What is combined in sexual fertilisation?
In sexual fertilization, a sperm cell from the male combines with the egg cell from the female.
How the sex of a person determined?
Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you are male you have the XY chromosome.. making you a male. If you are female you have the XX chromosome.. making you a female. It all depends on the father, if the father gives an X chromosome... you have a girl. Because it combines with the mother's X chromosome.. creating XX(a female) If the father give a Y chromosome.. you a have a boy. It combines with the mothers X chromosomes.. creating XY(a male)

How do you become a boy or girl?
Sex is determined by a pair of sex chromosomes. Males have XY chromosomes and females have XX chromosomes. In the fertilization stage where the sperm combines with the egg, the sex of the offspring depends on whether the sperm carries a X or Y chromosome. The ovum always carries a X chromosome because females only have X chromosomes. So, if the sperm carries the X chromosome, the offspring will have XX chromosome and becomes a girl. If it carries the Y, the baby becomes a boy. X (sperm) + X (egg) = XX (female) Y (sperm) + X (egg) = XY (male)

How do you determine to give birth to a male?
You cannot control the sex of a fetus through determination alone. The mother donates an X chromosome via her egg. The sperm donated by the male partner, which can contain an X or Y chromosome, determines the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).http://www.science20.com/news_releases/chromosomes_are_so_20th_century_male_genes_really_determine_baby_gender_says_study#ixzz3eHLpJJRt
Why double fertilization is advantageous for plants?
A single pollen grain has 2 sperm. Double fertilization occurs when 1 of these sperm combines with the egg, and the other sperm combines with a cell (this is called endosperm) That is in order for the seed to keep being produced.Seed has to be germinated, and without the extra sperm (double fertilization) the plant couldn't germinate and would go extinct.
