Consider two pure-breeding strains of mice (naked and hairless), each homozygous for an independently discovered recessive mutation that prevents hair formation on the body. When naked and hairless mice were crossed with each other, all offspring were phenotypically wild type. A self cross of F1 mice resulted in 115 wild type mice and 85 mutant mice. The number of genes involved are ; the best explanation for these numbers is :

Galaxy whose shape seems different follow no set pattern are classified as

The seed coat's most important function is to provide a) a nonstressful environment for the megasporangium. b) the means for dispersal. c) dormancy. d) a nutrient supply for the embryo. e) desiccation resistance.

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.
