What did gregor mendel contribute to science? a) he named alleles. b) he described the results of genetic crosses. c) he developed the punnett square. d) he named the gene.

The correct answer is option (B) He described the results of genetic crosses.

Gregor Mendel discovered the fundamental laws of inheritance through his work on pea plants. He studied the inheritance pattern using seven different traits of pea plants like the height, flower color, seed color, seed shape, flower position, pod shape and pod color by crossing numerous plants with contrasting characters, described the results of the genetic crosses and introduced the laws of inheritance.

The term gene was coined by William Johannsen in 1909 to describe the fundamental physical and functional units of heredity. Reginald Punnett and William Bateson devised the Punnett square to depict the number and variety of the genetic combinantions. The term “allele” was coined by William Bateson and Edith Rebecca.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
