Consider this:
Each parent has two sex chromosomes.
The mother, as a female, has chromosomes XX.
The father, a male, has XY.
The mother will pass on one sex chromosome to the baby, as will the father.
The mother can only pass on an X.
The father, however, has a 50/50 chance of passing on an X or Y.
XX would make a female and XY would make a male.
Simply put, the sex chromosome from your mother is fixed, it's going to be an X no matter what. It's which sex chromosome your father passes on that determines your sex.
Answer: Anaphase is a stage during eukaryotic cell division in which the chromosomes are segregated to opposite poles of the cell. The stage before anaphase, metaphase, the chromosomes are pulled to the metaphase plate, in the middle of the cell.
Explanation:
Answer: During photosynthesis, CO2 is absorbed and oxygen is released, whereas during cellular respiration, oxygen is absorbed and CO2 is released.
Answer:
The correct answer is option D) six dominant and two recessive.
Explanation:
The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).
Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.
Thus, the correct answer is option D) six dominant and two recessive.
