Answer:
prenatal environments
Explanation:
Depending on the number of fertilized eggs and when the zygote division occurs, there are different types of twins. For example, If the zygote is formed by the union of an ovule and a sperm that after fertilization is divided to create two embryos, they are born identical twins, these babies carry the same genetic information.
Answer: A,B and C
Explanation
The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.
We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.
Answer:
Because bananas are a good source of potassium and magnesium. And milk gives you calcium which both help ease and relieve muscle cramps.
