Genotypes indicate the genetic make up of a trait. Phenotypes indicate the look or external features of a trait. A brown eyed person may be genotypically brown and blue but phenotypically brown.

2015年11月29日 · Phenotype is the morphology of an organism . The genotype is expressed as phenotype when the information encoded in the genes is used to make protein and RNA molecules. Consider an example : Here , we have crossed a heterozygous ( the two alleles show dominant and recessive relationship vix T and t ) male gamete with a heterozygous female …

2014年6月15日 · The genotype is the combination of alleles (gene forms) and the phenotype is the trait or enzyme produced from the genotype. The phenotype is determined by the genotype. Below, we see the genotype listed on the lefthand column and the phenotype listed in the righthand column as well as in the corresponding images.

#p^2="frequency of homozygous dominant genotype"# #2pq="frequency of heterozygous genotype"# #q^2="frequency of homozygous recessive genotype"# From the question, we know that #98# of #200# individuals express the recessive phenotype. This means that these #98# also have the homozygous recessive genotype, the frequency of which is equal to #q^2#.

2015年11月3日 · Phenotypes are genotypes that have interacted with the environment. The genotype is an individual's collection of genes. The phenotype is the expression of the genotype in a certain environment. It means that two clones, with exactly the same genotype, will not look the same (will have different phenotypes) if they are raised in different environments. Here, the …

2017年9月22日 · Genotype means all genes in the organism. While phenotype is the expression of all genes. I shall explain the thing in a different manner. Everybody knows how to prepare tea. The ingredients of tea are tea leaves, hot water, milk and sugar. The ingredients are the genes. If you prepare tea like doing chemistry experiment, have fifty ml of hot water in a mug, add half a …

2016年11月8日 · The pheotype is morphological appearance of organism. The phenotype ratio of Punnet Square is 9:3;3:1 i.e., Walnut-9, rose-3, pea-3 and single-1.

2016年5月26日 · Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA ! - Let us start the story at the level of an eukaryotic diploid cell. There is a nucleus, inside which you see chromosomes in pairs. These are called homologous …

2018年3月7日 · Consider the following explanation: Genotype is the genetic complement of a phenotype (phenotype is actually the form of appearance of a trait). For example, consider a trait for seed shape in pea plants. Seed shape can either bametend or Wrinkled. Now, Round/Wrinkled is the phenotype and R R or Rr for Round while rr for Wrinkled is its genetic complement or …

2018年1月30日 · 25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous. In this explanation, I'm assuming that the allele "T" for tall plants is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment. A …
