What is epistasis?
When one gene controls the others
When one gene is recessive to the others
When one gene is codominant to another
When there are multiple alleles for one gene
Why are linked genes not always inherited together?
Crossing over occurs during meiosis
The chromosomes separate during anaphase
Linked genes are on different chromosomes
Genes are always inherited independently
If someone is a biological male, what are their sex chromosomes?
XX
XY
AB
23
Why does the X-Chromosome affect more traits than the Y-Chromosome?
X chromosome is smaller than the Y chromosome
X chromosome is larger than the Y chromosome
X chromosome is dominant to the Y chromosome
X and Y chromosomes are incompletely dominant
Why will males always express the recessive version of an x-linked trait?
Males have 2 X chromosomes
Males only have 1 X chromosome
Male chromosomes are always incompletely dominant
Males have more chromosomes
