Answer and Explanation: The cross between a green pea plant (Gg) and a yellow pea plant (gg) is shown below: From the cross, we can see that the possible genotypes are green and yellow.
What is the genotype of GG and GG?
Now, a pea with t he genes GG will be green is color, gg is yellow, and Gg is green due to the dominant gene, G. The GG, Gg, and gg above are known as genotypes. They denote the specific genes for that trait. The colors, yellow and green, are known as the phenotype, or the physical appearance of that genotype.
What is the genotypic ratio of GG and GG?
1/2
The two alleles of any gene are segregated during the formation of gametes. Thus the green-pod parent (Gg) will produce two kinds of gametes-G and g. The yellow-pod parent (gg) will produce g gametes. As you can see, 1/2 of the offspring are genotype Gg and 1/2 are gg.
What would be the possible genotypes of yellow peas?
The yellow pea phenotype has a genotype of AA.
What would be the phenotype for pod color of a pea plant with the genotype GG GG GG Why?
The physical expression of a genotype that can be visually observed is known as a Phenotype. a pea plant has a yellow pod phenotype, its genotype may either be GG or Gg. phenotype (green pods), then the individual parent having the dominant phenotype must be heterozygous.
What will be the phenotype of the offspring of green seeds GG and yellow seeds GG?
Since the Y (yellow) allele is dominant over the G (green) allele for pea plants, 100% of the YG offspring will have a yellow phenotype, as Mendel observed in his breeding experiments.
What does GG mean in biology?
Organisms that have two different alleles for a gene are called heterozygous (Gg). The offspring of the cross between the GG (homozygous dominant) and gg (homozygous recessive) plants are all heterozygous for the pod color gene.
What is the probable offspring of a true yellow pea pod GG and a true green pea pod GG?
Answer and Explanation: The cross between a green pea plant (Gg) and a yellow pea plant (gg) is shown below: From the cross, we can see that the possible genotypes are green and yellow. 50% of the offspring will have a Gg phenotype and 50% will have gg phenotype.
How do you find the genotype ratio?
To estimate the genotypic and phenotypic ratio, calculate the number of Punnett squares with each allele combination. So, in this example, one Punnett square for both RR and rr and two Punnett square boxes for Rr. Calculating Punnett square ratios as 1:2:1 will give the genotypic ratio.
How do you determine a genotype?
To determine a genotype, you can use a Punnett square. If you are working in a more advanced laboratory, you can use analytical methods such as PCR analysis and nucleic acid hybridization to determine what genotypes are present.
What are the 3 types of genotypes?
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
What would result from a yellow round pea crossed with a green wrinkly pea?
Answer and Explanation: A cross between a heterozygous yellow, round pea (YyRr) and a homozygous green, wrinkled pea (yyrr) will produce heterozygous yellow, round pea (YyRr), yellow, wrinkled pea (Yyrr), heterozygous green, round pea (yyRr) and homozygous green, wrinkled pea (yyrr) offspring .
What are the possible genotypes of the pea plants?
The possible genotypes are PpYY, PpYy, ppYY, and ppYy. The former two genotypes would result in plants with purple flowers and yellow peas, while the latter two genotypes would result in plants with white flowers with yellow peas, for a 1:1 ratio of each phenotype.
What are the possible offspring if a heterozygous green pod is crossed with homozygous yellow pad?
Therefore, in a cross between one parent who is heterozygous for the dominant green trait and one who is homozygous for the recessive yellow trait, the probability that the offspring will have a green pod is 50 percent.
What are the possible offspring genotype if you crossed heterozygous tall TT and homozygous dwarf TT plant Brainly?
In a cross between heterozygous tall plants (Tt) and a homozygous dwarf plant (tt), the ratio in the offspring shall be 1 tall : 1 dwarf. This is because the heterozygous plant will make two types of gametes, one type having T allele and the other having t allele. Hence, the correct answer is ‘1 tall : 1 dwarf’
What genotype means?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes.
When a pea plant with pure green pods GG crossed with pure yellow pods GG F1 generation off springs will be?
Since G is the dominant allele, so all the progenies will have green pod.
How do you solve a Punnett square?
How to Solve a Punnet Square
- Determine the genotypes (letters) of the parents. Bb x Bb.
- Set up the punnet square with one parent on each side.
- Fill out the Punnet square middle.
- Analyze the number of offspring of each type.
What are the 4 types of genotypes?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
What is AA and AA genotype?
Genotype AA is the universally compatible genotype that is, regardless of who they partner up with, there is no possibility of them birthing a child with sickle cell disease. Here are the compatible and incompatible genotypes: AA + AA = compatible. AA + AS = compatible. AA + SS = compatible.
What is F2 genotype?
What is the F2 generation genotype? The F2 generation genotype includes an expected outcome of 25% homozygous recessive, 50% heterozygous and 25% homozygous dominant individuals among the offspring.
