study

if you don't study you won't learn
The country in which Joseph is living is a least developed country (LDC), also often referred to as a ''third world country''. This type of countries are the countries that are at the bottom in pretty much every parameter used for measuring the quality of the human life. The government and the public institutions are corrupt, and also available for only certain people, the infrastructure is terrible, the industry undeveloped, the economy in dire condition, education is of very low quality...
These types of countries though are the ones that have the highest fertility rates, often the average being between 6 and 8 children per woman. Unfortunately, because of the bad conditions lot of those children die as infants or in the early childhood, on top of that the life expectancy is very low, usually in the range between 40 and 50 years of age.
I believe it was during the Eocene..
Hope this helps :) ~
Answer:
d) diploidy
Explanation:
PKU is a genetic condition caused by changes in genes and are transferred through generations in a recessive inheritance pattern. PKU is caused by mutations in the gene PAH phenylalanine hydroxylase (PAH) which codes for an enzyme (type of protein) called phenylalanine hydroxylase. PKU is caused by an Autosomal recessive pattern i.e A person must have a mutation on BOTH of his/her two copies of the PAH gene in order to have PKU and this only occurs if both parents are carriers for PKU.
Now , What maintains the presence of this harmful allele(The recessive allele that causes phenylketonuria (PKU)) in a population's gene pool?
NOTE the word recessive!
The answer is Diploidy.
This is because, the term diploidy refers to a state of having two sets of the chromosomes (and therefore two copies of genes), especially in somatic cells. Therefore, the usefulness of this is to stabilize the chromosome if one of the chromosome(i.e one copy of the gene) is a carrier of PKU.
