Which statement best summarizes gregor mendel's contribution to science?
a.
factors for traits in pea plants cannot be controlled.
b.
wrinkled seeds grow faster than smooth seeds.
c.
garden pea plants can be grown in a variety of colors.
d.
factors for some traits are inherited from parents.

The correct answer is-

D.  Factors for some traits are inherited from parents.

Gregor Mendel studied certain traits in pea plant and deduce the pattern of their inheritance using various experiments. According to Mendelian inheritance pattern, a characteristic or trait in an organism is depicted by single gene loci.

In other words, a single gene that exist in two alternative forms ( also known as alleles, which are dominant and recessive allele) depicts a particular trait (such as pea shape, pea color, height of pea plant).

He discovered that for some traits in organisms, factors are inherited from parents to their offspring ( that is from one generation to another) and these factors were later called genes ( also known as unit of heredity).

Thus, option D) is the right answer.

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
