One is Drosophillia melanogaster, a common genetic workhorse and common fruit fly. It has only four chromosomes.
All of the composite numbers less than 100 have factor pairs.
All quadrilaterals except parallelogramshave less than 2 pairs of parallel sides.

There are eight twin prime pairs less than 100 [(3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73)].
Autosomes come in pairs usually (one from the mother, and one from the father), but, sometimes, as in with genetic disorders, you might find things like trisomies, where you have 3 chromosomes for the same autosome, or monosomies, where you only have 1 instead of two.
Regular people have 23 pairs of chromosomes. Having less than that is not good.
There are a total of 23 pairs (22 chromosome pairs, plus another pair determining sex) for a total of 46 chromosomes for a normal human being. There are various chromosomal abnormalities in which an individual may have more than (trisomy) or less than (monosomy) than 46.
Chromosomes that are not X or Y are called homologous chromosomes and autosomal chromosomes. The first 22 pairs of human chromosomes are autosomal.
All of the composite numbers less than 100 have factor pairs.
Pairs with common factors other than 1.
They have less chromosomes than a normal cell.
same traitsthe same traits as each other. Different chromosome pairs code for different traits than other chromosome pairs do though. Only homologous chromosomes (chromosome pairs) code for the same trait as each other.
80 has 5 factor pairs.
12 and 18 have three factor pairs.
12 and 18 have three factor pairs.
After fertilization all normal human cells contain the same number of chromosomes as the cells of an adult human - 23 pairs of chromosomes, for a total of 46 chromosomes. Before fertilization the ovum contains only 23 chromosomes. A second 23 chromosomes are provided by the sperm during fertilization.
All humans, other than those with genetic disorders such as Down Syndrome, have 23 pairs of chromosomes, no matter what their skin color is. Skin color does not have anything to do with how many chromosomes a person has.
