Which punnett square shows the result of a cross between two heterozygous parents?
A cross between two heterozygous parents (eg. Gg X Gg) would result in a phenotypic ratio of 3 dominant : 1 recessive, and a genotypic ratio of 1GG:2Gg:1gg.GgGGGGggGggg
What blood types are possible from an B positive and A positive parent?
It depends what the second gene for each parent is. Bx+ and Ax+ is the information given. The x could be B for Bx and A for Ax. The x could also be O for both. So AA and BB or AO and BO. In all cases the cross between AA and BB would produce AB. For the cross between AO and BO, the result would be AB, BO, AO, and OO in a 1:1:1:1 ratio. If the cross is AA and BO, the result would be AB and AO in a 1:1 ratio. If the cross is BB and AO the result would be AB and BO in a 1:1 ratio. In all cases the Rh factor would be +
Is a Monohybrid Cross the same as a punnet square if not what's the difference?
A punnett square is the diagram used to determine the expected genotypic ratios for the offspring.A dihybrid cross is a cross involving two different traits. For example RrDd X RrDd would be a dihybrid cross. You could use a punnett square to determine the expected ratios for this cross:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrddOne parent's genotype is shown across the top, the other down the side (both in bold).
When doing a genetic cross why is it necessary to remove the parent flies before the pupae have hatched?
Usually, the parent flies will have a different genotype to the F1 generation (their offspring). For example, if the parents had WW (black eyes) and ww (white eyes), their offspring would all have Ww (black eyes). If you were experimenting further, you would want the F1 generation to cross - with Ww X Ww. If you did not remove the parental generation, you could have crosses between them and the F1 generation, which would result in different genotypes. If the parents were not removed, you could have the following crosses: Ww X WW Ww X ww WW X ww Ww X Ww The only cross that you would desire in the experiment would be F1 X F1 (Ww X Ww), which would give you the desired genotypes for the F2 generation.
Is RR X Dd a dihybrid cross?
The cross RR X Dd is showing two different genes for the parents (it is showing RR for one parent and Dd for the other) - therefore this is not a dihybrid cross. However, if it was RRDd X RRDd, this would be a dihybrid cross. For a dihybrid cross, you need to include two different genes (and show these genes in both the parents). So - BbFf X bbff, GGTT X ggtt, KKPp X KkPp - are all examples of dihybrid crosses.

What is the difference between the x- intercept and the y- intercept?
The y-intercept is where the line crosses the y-axis, and the x-intercept is where the line cross the x-axis
What is the generation of the offspring of a cross between parents that are pure for a given trait?
The first generation cross, known as F1 (filial 1), for homozygous (purebred) parents will be heterozygous - have one allele of each of their parents' traits. For example, the cross BB X bb would result in an F1 genotype of Bb.
What is the duration of X-Cross?
The duration of X-Cross is 1.5 hours.
If you were to cross pink flowering four o'clocks with white flowering four o' clocks what results would you expect Provide a punnett square to support your answer?
The cross would result In 50% pink and 50% white.
When was X-Cross created?
X-Cross was created on 2007-12-01.
When does the magnitude of dot product and cross product of vectors is equal?
If x is the angle between the two vectors then the magnitudes are equal if cos(x) = sin(x). That is, when x = pi/4 radians.
Which line is x?
x is a-cross
In a BB x bb cross?
in a Bb x bb cross?
What is the difference between force and stress?
Force = Mass x Acceleration Stress = Force / Cross Sectional Area
