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.
What is a all Ww Offspring?
All Ww offspring refer to the genetic outcome of a cross between two organisms where one is homozygous dominant (WW) and the other is heterozygous (Ww) for a particular trait. In this scenario, the possible genotypes of the offspring would be either WW or Ww. Thus, all offspring would display the dominant trait associated with the W allele, but 50% would be homozygous (WW) and 50% heterozygous (Ww). Therefore, all offspring would express the dominant phenotype, but their genotypes would vary.
Which parent combinations yield only white offspring?
To yield only white offspring, both parent organisms must carry the alleles for white coloration. In genetics, if white is a dominant trait, then a combination of two homozygous white parents (WW x WW) or a homozygous white parent (WW) with a heterozygous parent (Ww) will produce only white offspring. If white is a recessive trait, only two homozygous recessive parents (ww x ww) will produce exclusively white offspring.

What are the probability genotype of the parents?
ww ww
What is the ratio for Ww xx Ww?
The ratio for a genetic cross between two heterozygous individuals (Ww x Ww) follows Mendelian inheritance. The possible genotypes from this cross are 1 WW, 2 Ww, and 1 ww, resulting in a genotypic ratio of 1:2:1. If focusing on the phenotypic ratio, assuming W is dominant over w, the ratio would be 3:1 (with 3 showing the dominant trait and 1 showing the recessive trait).

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.
What is a all Ww Offspring?
All Ww offspring refer to the genetic outcome of a cross between two organisms where one is homozygous dominant (WW) and the other is heterozygous (Ww) for a particular trait. In this scenario, the possible genotypes of the offspring would be either WW or Ww. Thus, all offspring would display the dominant trait associated with the W allele, but 50% would be homozygous (WW) and 50% heterozygous (Ww). Therefore, all offspring would express the dominant phenotype, but their genotypes would vary.
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.
Tthe probability that two heterozygous parents for widow's peak will have a child with a straight hairline is what percent?
In genetics, widow's peak is typically represented as a dominant trait (W), while a straight hairline is recessive (w). If both parents are heterozygous (Ww), their offspring can be represented by a Punnett square, which shows the possible genotypes: WW, Ww, Ww, and ww. Only the ww genotype results in a straight hairline, which occurs in 1 out of 4 possibilities. Therefore, the probability that two heterozygous parents will have a child with a straight hairline is 25%.
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 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.
