scientific study of heredity
The ________ and inherited variation is known as genetics.
haploid sets of chromosome
The resulting fertilized egg, or zygote, is diploid because it contains two ________- bearing genes representing the maternal and paternal family lines.
bdelloid rotifer
A(n) ________, an animal that reproduces only asexually.
Karyotypes

microscope
Are stained when they are most condensed- during metaphase- and then seen via a(n) ________ using a digital camera.
Nonsister chromatids
________ are one maternal and one paternal chromatid in a pair of homologous chromosomes.
Bdelloid rotifers
________, it turns out, are an exception to the norm that sex alone creates genetic diversity: Other than sexual reproduction, bdelloids have ways for creating genetic diversity.
