In a genetic class pure green and yellow pod cross what would be the genotype of f1?

This is one of the classic experiments carried out by Gregor Mendel.
If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive.
To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.

How can you do a genetic cross to identify the P genotype?
The genotype of the P (parent) generation can be done by crossing an offspring from the F1 (first filial) generation with one of the gametes from the P generation and then calculating the genotypic and phenotypic ratios. Such an experiment is called a back cross
In a dihybrid cross between individual with the genotype RRYYand an individual with the genotype rryy all of the offspring with have the genotype?
RrYy
When trying to find an unknown genotype you must perform a?
Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.
Yy is the what of an individual?
A cross involving only one trait is a ? Cross
How do you identify the genotype?
normal sexual cross pollination - each parent plant contributes traits from its genotype (which are expressed as the phenotype)
How can you do a genetic cross to identify the P genotype?
The genotype of the P (parent) generation can be done by crossing an offspring from the F1 (first filial) generation with one of the gametes from the P generation and then calculating the genotypic and phenotypic ratios. Such an experiment is called a back cross
According to Mendel a cross between two round yellow peas both with the genotype RrYy would result in mostly peas?
round, yellow
What is the purpose of the punnett square?
Finding the genotype ratio for a cross.(Apex)
In a dihybrid cross between individual with the genotype RRYYand an individual with the genotype rryy all of the offspring with have the genotype?
RrYy
What is pheonotype?
Phenotype is the physical appearance of an organism. Genotype is the genetic makeup of an organism. For example, if you cross two plants that have the genetic makeup RR for flowers (let's say they're red), then the offspring will all have RR for flowers (homozygous red). The genotype is 100% RR, and the phenotype is 100% Red.
What is genotype AS SS AAA?
You cannot do a cross to determine the genotypes of individuals because there is only one gene here. Genotype consists of the entire genetic makeup of the individual, which cannot be determined by a single gene. Only the alleles S or s is used to express this particular gene. If you're looking for a monohybrid cross between Ss and Ss, while separately wanting a result between ss and ss, then the answers are as follows: Ss x Ss 25% SS 50% Ss 25% ss ss x ss = 100% ss

Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.

What is the important of test cross?
to determine the unknown genotype.
If you cross a while flower with the genotype pp with a purple flower with the genotype pp the possible genotypes in the offspring will be what for the cross what would the phenotypes be?
half white and half purple
What is a testcross?
Gregor Mendel devised the fundamental tool of the test cross. It is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype .
Perform the following cross wwgg x WwGg What percent of the offspring will be wrinkled green?
If you cross wwgg x WwGg, each parent contributes one allele for the traits. The genotype for wrinkled (w) and green (g) seeds is wwgg, and the genotype for WwGg is heterozygous for smooth and yellow. Therefore, 0% of the offspring will be wrinkled green.
