Mendel kept careful numerical data describing the results of his pea experiments. He knew that if alleles segregated randomly when forming gametes, mathematical probability should predict the outcome of the F2 generation. His true-breeding parent plants were homozygous, RR or rr. This cross resulted in an F1 generation of heterozygous plants, Rr. 1. What phenotypes would you predict in the F2 generation?

Explanation:

As given;

Parents are RR and rr,

All F1 progeny are Rr, They all  are heterozygous.

R is dominant on r, So R show his character  in heterozygous condition.

F2 generation are;

F1 are Rr and Rr, for F2, they are parents here

so gamets are R,r,R,r

F2 = RR,Rr, Rr rr

RR, Rr show dominant character, while rr show recessive character.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
