A genetic cross of inbred snapdragons with red flowers with inbred snapdragons with white flowers resulted in F1-hybrid offsprin

g that all had pink flowers. When the F1 plants were self-pollinated, the resulting F2-generation plants had a phenotypic ratio of 1 red: 2 pink: 1 white. The most likely explanation is what mode of inheritance

Answer:

The correct answer is - incomplete dominance type of inheritance.

Explanation:

Incomplete dominance is a type of inheritance pattern where the heterozygous condition of the alleles leads to the blend of both dominant and recessive alleles phenotype. In this case, red snapdragon and white snapdragon flowers crossed and produced pink flowers, which is a blend of both traits due to incomplete dominance of the red or dominant allele.

In such a pattern, the heterozygous condition only shows the mix or hybrid phenotype and parental phenotypes reappear in F2 when heterozygotes are crossed.

Answer:

A mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate, used as a source of chemical energy. They were first discovered by Albert von Kölliker in 1880 in the voluntary muscles of insects.

Which statement is true? Membrane phospholipids always comprise the majority (by weight %) of a cell membrane. The fluid mosaic
Maksim231197 [3]

Answer:lipid bilayer are essentially impermeable to polar solutes

Explanation:the cell membrane is a phospholipid bilayer.it is composed of lipids,proteins and carbonhydrates attached.the lipid bilayer forms the bulk of material on the membrane as a result it is impermeable to the movement of polar molecules in and out of the cell.small and non polar substances can pass through the bilayer of the membrane. the lipids and proteins occurs in varying composition in the membrane, depending on the

cell .the membrane has both a hydrophobic end and a hydrophilic end.the hydrophobic ends of the membrane folds toward each other.while the hydrophilic end is exposed to the water phase.the membrane is very flexible and thin and acts as a barrier that separates the cells external and internal environment

What is the phenotype(s) you can expect from crossing a pure round parent and a
nikklg [1K]

Answer:

Round

Explanation:

Round is the dominant phenotype and wrinkled is the recessive one. When crossing, the offspring will have one allele from each parent, i.e. Rr, wrinkled phenotype will hence be masked by the dominant round one.
