If the alleles for traits in pea plants did not segregate during gamete formation and offspring that were recessive for a trait could be produced only by crossing two plants that where recessive?

In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
What are the sources of variation in the offspring produced by sexual reproduction?
Random assortment & crossing-over
Producing offspring from parent with different forms of a is called crossing?
its called a hybrid
What would mating between a true breeding purple flowered pea plant and a true breeding white flowered pea plant produce?
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white
When gene are linked the reason a few of the recombinant genotypes still occur in the offspring is because of?
Crossing over.
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.

What is crossing a homozygous dominant or homozygous recessive with a heterozygous?
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
What percent of the offspring will display the recessive trait if parent 1Tt crosses with tt?
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
If 240 plant offspring were produced from crossing two heterozygous plants how many would be homozygous?
120 on average or 50%. 25% would be homozygous dominant and 25% would be homozygous recessive. The remaining 50% would be heterozygous.
What is a F1 cross?
F1 cross is the crossing that takes place at the first filial generation before the second filial generation.In this crossing,two homozygous parents are crossed together to get one homozygous offspring and three heterozygous offspring which will give a phenotypic ratio of 3:1. First filial generation is also the phase where the production/crossing started.I hope i av been able to answer your question to my own knowledge as a baby microbiologist
Crossing over the chromosomes results in greater genetic variability in offspring than if crossing over had not occured?
true
What is the percentage of crossing 2 parents for the same traits in the offspring?
My Nan.
What process results in the formation of chromosome c from chromosomes a and b?
crossing over
What holds doubled chromosomes?
Formation of chiasmata during crossing over
Crossing organisms from the F1 generation produces what generation?
Crossing organisms from the F1 generation produces the F2 generation.
What creates a variety in the offspring?
Genetic recombination during crossing over in prophase I of meiosis.
