Pollen is a gamete therefore it contains half genetic information of a regular cell. all the possible combination types are S1T, S2T, S1t and S2t
The three most important Mendel law is the law of dominance, law of segregation, and law of independent assortment. The law of dominance is when a trait is more recived or more dominate than other trait. For example a flower, if a flower is red most of the flowers will be red, but one will be white. The white flower has a recessive trait. The law of segregation is when a offspring randomly receive one allele of every trait from each parent. The law of independent assortment states that just because you received one allele doesn't mean another dominate allele will be passed also.
Answer:
The correct answer is e. all of the above
Explanation:
A person can only have two allele of a character, therefore, the genotype of a male parent can be IBIB or IBi and the genotype of female parent can be IAIA or IAi. Therefore during gamete formation, all allele will segregate and assort independently.
So all the possible combinations are possible that are IAIB, IAi, IBi or ii because all the allele can be present in the two parents in which one have A blood group and another have B blood group.
Therefore their children could have A, B, AB, or O blood group so the correct answer is e. all of the above.
The immune system.
The immune system acts as a defense system of the body. It fights against bacteria, viruses and any other disease causing pathogens. Some chemicals can weaken the immune system and make them vulnerable.
