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.
If red flowers were cross with white flowers and all the resulting flowers were pink. what percentage of a cross between two pinks would be pink?
Let RR = Red and WW = White and RW = PinkRR X WW = RW (all resulting flowers are pink)Punett Square of pink cross pink:RWRRRRWWRWWWAs you can see, 50% are pink, 25% are red, and 25% are white.This is an example of incomplete dominance in flower colour.
A plant can have either broad leaves or narrow leaves What cross is represented by the by the Punnett square shown below?
Ww
In fruit flies straight wings are dominant and curly wings are recessive. What will the generations look like?
If we cross a homozygous dominant fruit fly with straight wings (WW) and a homozygous recessive fruit fly with curly wings (ww), all offspring in the first generation (F1) will be heterozygous (Ww) and exhibit straight wings. If we then cross two F1 flies (Ww x Ww), the second generation (F2) will show a phenotypic ratio of 3 straight-winged flies to 1 curly-winged fly, resulting in about 75% straight wings and 25% curly wings.
What is the ratio of a white snap dragon crossed with a pink snap dragon?
if you mean in terms of what their offspring will be? then you need to do a monohyrid cross, the gametes being RW and WW sooo x R W W RW WW W RW WW it will be 1:1 ratio of pink to white offspring

What is individuals having two of the same alleles of a gene?
A monohybrid cross is a cross between two individuals that are homozygous for different alleles of the same gene. An example is a cross between a red-eyed (RR) fruit fly and a white-eyed (WW) fruitfly.
Why did WW II happen?
WW II was largely the result of lingering resentment by Germany about the outcome of WW I. You could describe it in sports terminology as a rematch.
In a certain cat long whiskers (W) are dominant and short whiskers (w) are recessive. Two cats have genotypes Ww and ww. If they have an offspring with short whiskers what is the genotype of their off?
ww
What was the difference between the first and World War 2?
The most important different between WW I and WW II is there is a lot modern weapons and atomic bombs are used in WW II.
Where is ww stadium in woozworld?
In between the "ooz".
Where was the WW1 Mackenzie line?
There was no piece of the WW I front that was called the McKenzie line. There was a famous soldier called McKenzie in WW I who received the Victoria Cross for bravery. He fought in Belgium.
Describe the offspring of a true breeding white flowering plant?
The offspring of a true breeding white flowering plant will also display white flowers because it carries two copies of the white flower gene. These offspring will be homozygous for the white flower trait and will consistently produce white flowers when they reproduce.
Suppose you have two mice one black one white the genotype for the black mouse is WW and the genotype for the white mouse is ww What would the punnet square look like?
It would look like this. --¦ W W -------------- w¦ Ww Ww w¦ Ww Ww All the offspring would be black-furred, all carrying one dominant gene and one recessive.
