What is genotype of the plant with colored seed and normal strach you used in the test cross?

Homozygous recessive; if 'r' stands for color of the seed and 's' for normal starch, then the genotype of this plant used in a test cross will be ( rrss ).

How do you identify the genotype?
normal sexual cross pollination - each parent plant contributes traits from its genotype (which are expressed as the phenotype)
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
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false

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 .
The mating of an individual of unknown genotype with one that is homozygous recessive in order to determine the unknown genotype is a?
Test Cross.
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
How can the unknown genotype of an individual with a dominate phenotype be determined?
A test cross.
What colored horses would you cross to get a gray colored one?
Since grey is a dominant gene any grey horse paired with any other colored horse has a chance of being grey, but the best way to ensure that the foal will be grey would be to breed two homozygous grey horses (in other words horses that have to grey alleles and and whose genotype could be shown as GG)
Which genotype is used in a test cross?
A homozygous recessive as male parent
