What are the possible genotypes of a yellow pod?
plants that have G in their genotypes have green pods. Only plants with genotype gg have yellow pods. In this example, 1/2 of the offspring have green pods and 1/2 have yellow pods.
What is the genotype of each offspring?
An offspring’s genotype is the result of the combination of genes in the sex cells or gametes (sperm and ova) that came together in its conception. One sex cell came from each parent. Sex cells normally only have one copy of the gene for each trait (e.g., one copy of the Y or G form of the gene in the example above).
What percent of the offspring are yellow?
The GENOTYPE is 100% HETEROZYGOUS. If two of these hybrids are now crossed, a second filial or F2 generation can be produced. There are 2 phenotypes. 75% of seeds will be YELLOW.
What is genotype ratio?
The genotypic ratio is the ratio depicting the different genotypes of the offspring from a test cross. It represents the pattern of offspring distribution according to genotype, which is the genetic constitution determining the phenotype of an organism.
What are the 4 genotypes?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
What is the genotype of the plant with yellow pods?
The genotype of the plant with yellow pods is aa. The genotype of the gametes produced by the heterozygous plant is 50% A and 50% a. The genotype of the gametes produced by the plant with yellow pods is 100% a. The expected frequency of F₁ plants with yellow pods is 50%.
What is the genotype of a homozygous Green offspring?
Therefore, if an offspring’s genotype is GG, then it is said to be homozygous green. If the genotype of the offspring is Gg, it is heterozygous, but still green as the color green is dominant to yellow. If the offspring is homozygous gg, then, it will be the recessive yellow color.
How do you determine the genotype of a pea plant?
In the P generation, pea plants that are true-breeding for the dominant yellow phenotype are crossed with plants with the recessive green phenotype. This cross produces F 1 heterozygotes with a yellow phenotype. Punnett square analysis can be used to predict the genotypes of the F 2 generation.
What is the genotype of the gametes produced by the heterozygous plant?
The genotype of the gametes produced by the heterozygous plant is 50% A and 50% a. The genotype of the gametes produced by the plant with yellow pods is 100% a. The expected frequency of F₁ plants with yellow pods is 50%. The expected frequency of F₁ plants with the genotype AA is 0%.
