male honey bees andantsreceive chromosomes only from the female parent (the Queen). This means that they develop from unfertilized (haploid) eggs and don’t have a father, whereas fertilized (diploid) eggs produce female progeny!

In this experiment, we tested whether interactions between X chromosomes might explain female sterility and inviability inT. commodusandT. oceanicus. We introgressed X chromosomes from either species onto recombinant autosomal backgrounds over three generations of crosses, and tested the fertility and viab...

Human chromosomes are made of DNA, protein, and glucose. True False Chromosomes Chromosomes are the thread-like structures that contain the DNA and it is found inside the nucleus of an animal or plant cell. Each human cell contains 46 chromosomes. After every cell division by mitosis, the...
Reptiles in general exhibit variability in sex-determining systems; as typical poikilotherms, they might be expected to have a rapid turnover of sex chromosomes. However, molecular data which would enable the testing of the stability of sex chromosomes are lacking in most lineages. Here, we ...
