Answer:
Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes
Explanation:
In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.

Answer:
what is the effect of food availability/competition on natural selection
Explanation:
Something along those lines, this is similar to the Galapagos finches when there used to be just one species but due to natural selection and limited food due to competition, the beaks changed to be able to eat the other food s available that they originally could not eat. There are now about 14 due to this.
I hope this helps u!
