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.
If you have a plant with yellow seeds which express a dominant phenotype. How would you determine the plant's genotype?
Identify the genotype trait of the seed color is yellow or green?
What proportion of the offspring from this cross will have smooth yellow peas?
9
What color leaves will you observe on the offspring of two green parent plant?
I think that you will have yellow becaues green color could make yellow.
What are the genotypes of the parental dogs one is black the other is brown who have ONLY black or yellow puppies. Explain how you determined their genotypes.?
BBEe and bbEe. Black is dominant, and brown is recessive. Yellow is also recessive. Because one parent is brown, for none of the puppies to also be brown the black parent cannot carry the recessive allele on the B locus. Because neither parent is yellow but some of the puppies are, both parents must carry the recessive allele on the E locus.
How many offspring of a heterozygous mating will have a dominant genotype for yellow fur?
25%
How was it possible that there were short plants in the f2 generation if there werent any short plants in the f1 generation?
The reason why short plants reappeared in Mendel's F2 generation of pea plants was because their short trait was heterozygous. Both parents carriedÊthat recessive gene, so they passed it on to their offspring.
A cross between two pea plants that produce yellow seeds results in 124 offspring 93 produce yellow seeds and 31 produce green seeds what are the likely genotypes of the plants that were crossed?
Yy
How is it possible for two individuals to have the same phenotype but a different genotypes for a trait?
it is possible beccause you dont always need both

Identify the genotype trait of the seed color is yellow or green?
The gene for white colored fruit is dominant over yellow fruit If 2 squash heterozygous for fruit color are crossed what will be the genotypic ratio of squash produced by the F1?
If two squash are heterozygous, it means they have a genotype with different genes. In this case, it would be Wy (a white gene and a yellow gene. y is lowercase because it represents that it is a recessive trait). If the parents are both Wy, if you create a Punnett Square, you get that the genotypes of the offspring will be WW, Wy, Wy, yy. Therefore, the ratio is 1:2:1 (since there are two Wy).
Is it possible for two parents with a yellow body color to have a blue offspring?
If they both are heterozygous and the recessive gene is blue it can happen
In tomatoes red fruit color is dominant to yellow and suppose a tomato plant homozygous for red is crossed with one homozygous for yellowso determine the appearance of first filial?
Let the dominant allele, red color, be represented by R,and the recessive alelle, yellow, by r. Both parent plants are homozygous, so their genotypes will be: Red: RR Yellow: rr The cross is therefore: RR X rr Remember that a homozygous genotype can produce only one type of gamete, so the red plant can only produce gametes with R, and the yellow plant can only produce r gametes. Since the F1 generation takes one gamete frrom each parent, and each parent can only produce one type of gamete, then the F1 generation can have only one genotype: F1: Rr That is, all of the offspring from this cross will be heterozygous. Red is dominant over yellow, and all of the offspring carry one R allele, therefore all of the F1 generation will be red in color.
If yellow peas are dominant over green peas the offspring of a pure dominant and a pure recessive cross is?
Let Y represent the dominant allele, and yrepresent the recessive allele. Let us also assume that "pure" means homozygous for that trait ("pure' is not the usual term for this, "homozygous" is) So, the two genotypes of the parents of the cross are: Parent 1: YY Parent 2: yy To solve a problem like this, one always has to determine what kind(s) of gametes each parent can produce. Both parents are homozygous for their respective traits, so in this case, each parent can only produce one kind of gamete: Parent 1 can only produce Ygametes, and Parent 2 can only produce y gametes. Therefore, every one of their offspring will have the following genotype: Yy Since every one of the offspring of the cross carries a Y allele, and Y is dominant, all of the offspring will be yellow.
If both parents are yellow and all offspring are yellow then?
You may have a canary.
What was the genotype of the plant that produced yellow pea F1 generation?
Yy
