Male infertility can come about generaly for reasons, they are? low sperm count & deformed sperm
This process allows a woman's egg to be fertilized by a male's sperm outside of the female's body. IVF
The idea that DNA is inherited entity rather than protein was concluded through the research group was lead by this person. Avery
The easiest way to analyze the transmission of a genetic trail in humans is through this type of analysis. Pedigree
This type of genetics allows researchers to study gene products and the actions of these products. Molecular Genetics

Three enzymes that are involved in the replication of DNA are? DNA helicase, DNA primer, DNA ligase
This is formed at/in a ribosome Amino Acids
Specifically, free nucleotides, which are used to construct new DNA molecules are found in this part of the cell Neucleoplasm
These are organelles that contain digestive enzymes Lysosomes
During DNA replication these segments are made. Okazaki
The molecule that brings an Amino Acid to a ribosome is tRNA
If multiple ribosomes assoicate with a single strand of mRNA this structure is called Polyribosome.

During the cell cycle a chronomosome will be composed of two chromatids from this point until this point. S-phase & anaphase
If an individual appear s to be in his 80's but is really only 40 this inidividual may be suffering from ? Werner's Syndrome
The chemical molecule that helps to dissolve the nuclear membrane and assists in condensing a DNA strand. MPF
If a cell doesn't have the appropriate molecular requirements this cell may not pass out of gap 1 and will enter this stage, (time of relative inactivitity within a cell cycle) Gap zero
The ability of a single gene to have multiple effects on one or more individuals is called? pleiotropy
The degree to which a gene's effect is seen in a person's phenotype is termed? Expressivity
In a Hh state, cystic fibrosis gives protection against this if this disease Cholera
The major cause of death for this disease is rupture of an aorta. Marfans
If 2 alleles of the smae gene both have the ability to make and simultaneously equally express proteins this condition is refered to as? Codominance
If multiple genetic states can affect individuals in the same way this is refered to as Genetic Heterogenetity
If a person is Hd for the recessive for the Bombay genotype this person with a genotype of AB for the ABO blood group will express a blood type of? O
For a polygenetic trait if a set of parents have the genotypes of AaBBCcddee and aaBbCcddEe the most dominant alleles the child can have is? 6
If a person has PKU they will need to eat a diet free of this aminio acid since they lacy a vital enzyme necessary to metabolize this item Phe (phenylalanine)
If 60% of the members in a population are Hh for autosomal recessive trait what is the probably of 2 Hh meeting, mating, and reporducting a child with the same genotype as the parents? 18% (.6*.6= .36 .36*.5=.18)

Individuals, both male and female, who bring new allese for a specific gene into an area founding fathers
When chromatids separate becoming chromosomes anaphase II
Formations that result when DNA wraps around a number of histones. Nucelosomes
The female structure that results after teh male gamete has entered the females developing gamete ootid
Hapolid Male cell that is a glob of cytoplasm spermatid
Points within a tetrad where the nonsister chromatids crossover chiasmata
Female structure that contains the dipolid number of replicated chromosomes primary oocyte
Mall cell that can begin the process of meiosis the cell that is the product of mitosis primary spermatocyte
spindle fibers attach to replicated chromosomes in a cell that has only one half the diploid number prophase II
Pairs of replicated chromosomes are found at an eqyal distance from each of the cell's poles metaphase I
Chromosomes composed of 2 chromotids are at the poles of the cell telophase I
Persons who have at least one common ancestor in the previous generations consanguinity
The chemical molecule that helps to dissolve the nuclear membrane and assists in condensing a DNA strand. MPF
