The answer is a because if u do a punnett square to get your results like i did, each plant would end up with the phenotype Y(yellow)y(green), and since they all have 1 dominant and 1 recessive, the dominant trait takes over, but the recessive trait is still there but it doesnt show up. 

hopefully my answer helps u

Mendel crossed plants that produced only round seeds to those that produced only wrinkled seeds. In the next generation, all the
Artist 52 [7]

Answer:

Dominance

Explanation:

Mendel discovered certain principles that governs heredity or inheritance when he conducted experiments. In his experiments, he discovered that an organism receives two copies of a gene called allele, from each parent.

He discovered that one allele of a gene has the ability to mask or suppress the expression of its allele variant in the same gene. He called the allele that masks or is expressed, DOMINANT allele, while the allele that is masked, RECESSIVE allele. Based on this observation, he named his first principle, LAW OF DOMINANCE.

In this case, he crossed a purebreeding round-seeded pea plant and a purebreeding wrinkled-seeded pea plant, he noticed that in the F1 generation, all the offsprings possessed round seeds. This led to the conclusion that the allele for round seeds masks the phenotypic expression of the wrinkled allele in a heterozygous state. Hence, the allele for round seeds is dominant while the allele for Wrinkled seeds is recessive.

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.
