What is the SRY genes and where is it found?
What is a linked gene?
is one of a pair of genes that tend to be inherited together
What are two types of sex- linked genes?
What is an example of a y-linked gene in humans?
Why are there more x-linked traits than y linked traits?
Is it more or less likely for a crossover to occur if two genes are far apart on the same chromosome?
the further apart a cross over will effect them
What is a map unit?
is an increment if 1 percent in the frequency of crossing over
What type of cells are germ cells?
What type of cells are somatic cells?
Are mutation harmful, helpful or can they be both?

Can a mutation involve an entire chromosome? One single DNA nucleotide?
can be involved in a whole entire chromosome
What happens with a deletion mutation? A translocation? A nondisjunction?
A deletion mutation is when a part of a DNA is loss from an chromosome. Translocation is the movement of a segment of DNA from one chromosome to another. Nondisjunction is the failure of homologous chromosome to separate.
What is an example of a nondisjunction mutation in humans?
sickle cell disease
What is a point mutation?
is a mutation in which only one nucleotide or a DNA is replaced with different nucleotide
What is a substitution point mutation? A frameshift point mutation? An insertion point mutation?
is when a codon is replaced for a different codon, iswhen there is an insertion and deletion of an codon and it shifts the reading frame, and
Do insertion, deletions and substitutions all cause frameshift?
insertion and deletion cause frameshift, but substitution does not cause frameshift
What does a circle stand for in a pedigree? A square? A horizontal line connecting a circle and a square?
circle is female,square is a male and horizontal stands for a marriage or a baby

What are multiple alleles? Example?
more than three or more alleles for a genetic trait, and blood type
What is an example of incomplete dominance? X- linked trait? Sex- influenced trait? Single allele trait?
