Homework Help: science CONFUSED

Posted by Amy L. on Monday, April 30, 2007 at 5:21pm.

I nead help with two questions. These to questions are confusing to me for some reason.

Explain how the inheritance of traits is controlled in organsims. Use the terms genes and alleled in your explanation.

The allele for round seeds is represented by R. Suppose that a pea plant inherited tow recessive alleles for wrinkled seeds. How would you write the symbols for its allelels/

Majoraly confused.
???????????????

please help

On the first, see....
http://en.wikipedia.org/wiki/Mendelian_inheritance

On the second. The round seed allele is R. The recessive would be a small letter, you could use w or r. If the seed had two recessive, you would write it as rr (or ww). If it had one recessive, and one round, it would be written Rr (or Rw)
