In his experiment mendel first crossed tall and short peas plant and noticed that the F1 plants were all tall. in the second experiment he crossed the the F1 plants and noticed that short plants reappeared in the rate of 25% in F2 generation. in his third experiment he crossed he crossed F2 plants and noticed that when he crossed some tall plants with the shot plants the F3 generation contained short plant in frequency of 50%. after this observations mendel concluded that there were genes that could be only expressed in homozygous state but not in heterozygous state. these genes were later referred to as recessive alleles wheres the genes that prevented the expression of recessive genes were later referred to as dominant genes.
<span>The most common type of material from a lunar explosion would be achondrite rocks. The moon's composition is low in chondrules therefore it contains more achondrite-like material.</span>
"It will increase the frequency of genetic mutations. *i think this one* It will result in reduced genetic diversity within the species. It will make the species unable to reproduce sexually. It will decrease the life span of the species." - hope that helps not my work tho some one else wrote this
i guess that is an endangered species but a threatened species is one whose habitats or survival is in danger mostly due to human factors like poaching and encroachment I guess
