cross a yyll (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). look at the number of phenotypes of the f1 generation. yyll x yyll (parents), crossed will give you these offspring:

yyll: 400

yyll: 100

yyll: 100

yyll: 400

If we have 1600 offsprings than

YyLl = Tall plant with round pea seeds = 400 out of 1600

Yyll = Tall plant with wrinkled pea seeds = 400 out of 1600  

yyLl = Dwarf plant with round pea seeds = 400 out of 1600 and

yyll = Dwarf plant with wrinkled pea seeds = 400 out of 1600

Explanation:

Taking an example of pea plant.

In this question each organism has heterozygous alleles i.e Yy of single character gene with having both dominant and recessive traits.  

Say for example in this case capital "Y" represents Tall dominant character and small "y" represents dwarf recessive character. Similarly Capital "L" for example represents round dominant pea seeds and small "l" represents wrinkled recessive pea seeds.  

In this question organism with having heterozygous characters (i.e having both dominant and recessive traits) are crossed. Underlined represents male part while non-underlined represents Female part of plant

                                YyLl × yyll(1)

Four different types of gametes are produced from each organism due to meiosis in which chromosomes become half and alleles become separated.

                 i.e YL, Yl, yL and yl × yl, yl, yl and yl(2)

Mating of these alleles are represented below in the form of checkerboard.

                  YL              Yl                yL            yl  

yl               YyLl           Yyll             yyLl         yyll

yl               YyLl           Yyll             yyLl         yyll

yl               YyLl           Yyll             yyLl         yyll

yl               YyLl           Yyll             yyLl         yyll  

In this cross Phenotype of F1 generations are

YyLl = Tall plant with round pea seeds = 4 out of 16

Yyll = Tall plant with wrinkled pea seeds = 4 out of 16  

yyLl = Dwarf plant with round pea seeds = 4 out of 16 and

yyll = Dwarf plant with wrinkled pea seeds = 4 out of 16

If we have 1600 offsprings than

YyLl = Tall plant with round pea seeds = 400 out of 1600

Yyll = Tall plant with wrinkled pea seeds = 400 out of 1600  

yyLl = Dwarf plant with round pea seeds = 400 out of 1600 and

yyll = Dwarf plant with wrinkled pea seeds = 400 out of 1600

the answer is c.) there is a warm front in region a and a stationary front in region b.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
