Answer:
The phenotypic ratio will be 3:1
Explanation:
As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.
The cross of true breeding plants as mentioned above is depicted as under:
Parents YY x yy
/ \ / \
F1 generation Yy Yy Yy Yy
So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.
Next, when these F1 plants will be crossed, the result will be as under:
F1 generation Yy x Yy
/ \ / \
F2 generation YY Yy Yy yy
The genotypic ratio of F2 generation is 1:2:1
The phenotypic ratio of F2 generation is 3:1
It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.
Agree
Explanation:
It is very correct that plants cannot walk and animals can't use energy from the sun.
Locomotion is the movement of body from one place to another.
The process by which plants manufacture their food using sunlight is called photosynthesis.
- Plants are fixed, sessile and cannot move about.
- Their root penetrate deep into the earth by which they derive their own nourishment.
- Walking is one attribute of higher animals.
- Manufacturing of food using sunlight is in the exclusive preserve of plants.

Answer:
mutated dna
Explanation:
there would be either be dna substitutions, deletions or insertions. substitution simply changes the letter. deletion gets rid of a letter. insertion adds another letter.
A single species that has evolved into several different forms that live in different ways has undergone "b. convergent evolution" since the multiple "divergent" species are seen to "converge" into a single species if you go back far enough in time.
