One character in peas that mendel studied was yellow versus green seeds. a cross between a homozygous yellow line (yy) and a homozygous green line (yy) will result in f1 plants that are heterozygous (yy) for this trait and produce yellow seeds.

The statement is true.

Explanation:

Gregor Mendel, the Father of Genetics, used pea plants as a model to study inheritance for several reasons, but mainly because they possess a diversity of phenotypic traits, such as different colors and shapes.

Mendel analyzed the inheritance patterns of parental genes in regard to how these genetic traits appeared in the phenotype of the offspring, he categorized these traits as dominant (two capital letters; AA) or recessive (two low-case letters; aa). To test this in the experiments, he selected yellow and green pea plants.

When he crossed yellow and green pea plants, he observed that the first generation exhibited the yellow phenotype. This indicated that the color yellow (YY) was the dominant one, while the green (yy) was, consequently, recessive.

Therefore, if we cross a homozygous yellow line (YY) with a homozygous green line (yy), the result of the First Generation (F1) will result in heterozygous plants with a yellow phenotype as demonstrated in the Punnett Square below:

       Y      Y

y     Yy     Yy

y     Yy     Yy

YY: Yellow

yy: Green

Yy: Yellow

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
