A species has homologous chromosomes. what does this say about the species?
It has pairs of matching chromosomes (APEX)
How many chromosomes does a germ cell contain?
23. Germ cells (sperm and egg cells) are haploid, which is to say they possess half of the total number of chromosomes found in somatic cells. Somatic cells in humans have two sets of 23 unique chromosomes for a total of 46 chromosomes.
Biologists use what symbol to represent one set of chromosomes?
The number of chromosomes in a cell is represented by the letter "n". A cell can be haploid (n or 1n), diploid (2n), triploid (3n), etc. A gamete is haploid and would be represented by n, or half of a diploid (2n). Some notations will say the chromosome number (in humans for example), n equals 23 or n=23. Likewise, a diploid cell would be denoted by 2n=46.
Do all species have the same number of chromosomes?
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
Does the number of chromosomes determine how complex an organism is?
No there isn't. Humans are much more complex than a fern, yet the Adder's Tongue Fern has 1262 chromosomes and a human has only 46. It also doesn't work the other way either (more complex organisms having less chromosomes) for fruit flies have 8 chromosomes and dogs have 78. Also, chimpanzees have the same number of chromosomes as potatoes and, surely, they are on different complexity levels.

What does mean to say a cell is disploid?
when the cell has complete chromosomes. For animal cells, diploid cells have 23 pairs of chromosomes

If a cell has 25 chromosomes is it a somatic cell or a diploid cell?
you cannot say if a cell is somatic or germ cell by seeing the number of chromosomes present in it. If a cell has one pair of each chromosome then it is reffered to as diploid. haploid is represented by 'n' whereas Diploid-2n Triploid-3n and so on. A somatic cell is the cell which is present in your body. A germ cell is the cell present in your Gonads(gonads are reproductive organs) such as testis and ovaries.they have the x and y chromosomes. so if a cell has 25 chromosomes, it might be a somatic or germ cell. it's ploidy can be haploid or diploid. this can be known only by obtaining a karyotype. a karyotype is the diagramatic representation of the chromosomes by detailed analysis. if this cell is diploid, it means that it is missing one of its chromosome. because diploid is 2n.
Do all species have the same number of chromosomes?
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
What does this say about the evolution of these two species?
They probably have a recent common ancestor

Do you agree or disagree that homologous chromosomes are found in gametes?
Have to say Nay. Two chromosomes are 'homologous' , to my understanding, only if each is IDENTICAL with the other - this means a pair. Gametes are haploid, meaning that only one copy of each (normally diploid or paired) chromosome (s) is (are) present.
How many chromosomes does a boar have?
How i know a wild boar have many different sub-species and they have never been properly genetically classified.The site i found say 36,37,38 and can be 40 chromosomes.

What does God say about species of animals?
God says animals & humans reproduce "kinds after kinds".
