________ is the actual combination of genes and how they are expressed in an organism. -
ANS Genetics
Normal human gametes carry _____ chromosomes. - ANS 23
Heredity is not about an exact passing down of the genetics it involves variation (true or false) -
ANS true
Sexual reproduction is a thing so you ______ have an identical copy of the parent - ANS do
not
Asexual reproduction is like cloning where you do want an exact copy (true or false) -
ANS true
In sexual reproduction you dont want an exact copy but you do want the same genes coding for
the same things to be there but you want them to be varied in their combinations. (true or
false) - ANS True
A _________ is looking at all the chromosomes in a particular organism - ANS Karyotype

, Human cells have _____ pairs of chromosomes - ANS 23
In humans 22 of our chromosomes are called __________ because they are non sexual
chromosomes - ANS autosomes
In the cell the 23 pairs of chromosomes in humans are lined up nicely (true or false) -
ANS false - they are jumbled up (they will pair up in meiosis)
A ___________ pair of chromosomes means that the same chromosome from each parent are
joined together and have the same structure - ANS homologous
In humans each cell has ____ individual chromosomes - ANS 46
__________ is when you only have 1 set of parental chromosomes - ANS haploid
_______ is when you have both sets of parental chromosomes - ANS diploid
If a cell has both homologs then it is ________ - ANS diploid
The center part of 2 sister chromatids that is pinched in is the _______ - ANS centromere
In homologous pairs, for example, the chromosome 1 from the mother and the father express
the same trait. (Hair color, eye color, etc) (true or false - ANS true
Although homologous pairs express the same metabolic genes the specific genes may be
different from one another. (Ex: blue eyes or brown eyes) (true or false) - ANS true
