2. Natural selection occurs at the level of the:
a) Individual
b) species
5. Which of the following is not an RNA base?
a) guanine
b) cytosine
c) thymine
d) adenine
17. In a cross of a homozygous dominant individual with green peas to a homozygous recessive individual with yellow peas, what are the expected genotype frequencies for the offspring?
a) 100% heterozygous
b) 75% green: 25% yellow
c) 100% green
Homework Answers
Answer2:-correct option is (b) species
because,this emphasis that selection of useful variations by the nature is the main (not exclusive) mechanism for evolution to occur.The phase survival of the fittest used by charles darwin as natural selection so evolution is change in genetic compostion of population
Answer5:-correct option is (c) thymine
rna has uracil at place of thymine.
answer17:-homozygous dominant with GREEN pea has genotype= GG
homozygous recessive with yellow pea has genotype= gg
cross between above produces genotype:-Gg,Gg,Gg,Gg.
so,all are heterozygous in nature.
correct option is (a)100% heterozygous
