a. Leptotene, Zygotene, Pachytene, Diplosomia, Telekinesis
b. Leptin, Zygotes, Polydactyl, Diplosomia, Diakinesis
Leptotene, Zygotene, Pachytene, Diplotene, Diakinesis
d. Leptin, Zygotes, Pachytene, Diplosomia, Diakinesis
Leptotene, Zygosis, Polydactyl, Diplotene, Diakinesis
Which of the following statements is
a. Genes are capable of existing in several states (alleles), each having
detectable effects. The change from one such state to another is known
b. Each chromosome has many genes, and these are arranged in a linear
The order of genes along a chromosome is altered through the process of
d. Every gamete receives one chromosome of each homologous pair. This
distribution of chromosomes to the gametes is a matter of chance.
e. The distribution to the gametes of the chromosomes of one homologous
pair has no effect on the distribution of the chromosomes of the other
you have performed the following dihybrid cross in Drosophila using the
body color (b) and
wings (vg) mutations.
The b+ (grey body) and vg+
(normal wing) are dominant wild type alleles.
These genes are autosomal.
