The principles of probability can be used to
predict the traits of the offspring produced by genetic crosses
In the P generation, a yellow pea plant was crossed with a green pea plant. If alleles did not segregate during gamete formation
all of the F1 plants would be green
I observe a cell going through some sort of meiosis and at the end there is one big cell and three tiny ones. What type of cell have i just watched form?
If you made a punnett square showing Gregor Mendel's cross between true-breeding tall plants and true-breeding short plants, the square would show that offspring had
a genotype that was different from that of both parents
if a pea plant RrYy is crossed with a pea plant RRYy how many different phenotypes are their offspring expected to show
A tall plant is crossed with a short plant. If the tall F1 pea plants are allowed to self polllinate,
some of the offspring will be tall, and some will be short
How many different allele combinations would be found in the gametes produced by pea plant whose genotype is RrYy?
How would I know I was looking at a trait controlled by more than one gene?
it would have a range of phenotypes with the majority of individuals having a moderate phenotype
I cross two fruit flies and observe the following phenotypic ration with their offspring: 9:3:3:1. Which of the following crosses was most likely the cross that produced this ratio?
When Gregor Mendel crossed a wrinkled pea plant with a smooth pea plant, the F1 plants inherited
an allele for smooth peas from the smooth pea parent and an allele for wrinkled peas from the wrinkled pea parent
If a pea plant has a recessive allele for wrinkled peas, it will produce
wrinkled peas if it does not also have a dominant allele for smooth peas
What principle states that during gamete formation alleles for the same gene separate without influencing each other's inheritance?
principle of segregation
A cross of a black chicken (BB) with a white chicken (WW) produces all gray offspring (BW). This type of inheritance is known as
In the punnett square which of the following is true about the offspring resulting from the cross
about half are expected to be short
In the P generation, a tall plant was crossed with a short plant. Short plants reappeared in the F2 generation because
the allele for shortness and the allele for tallness segregated when the F1 plants produced gametes
A situation in which phenotypes for both alleles of a particular gene are equally expressed is termed
In the P generation, a tall plant is crossed with a short plant. The probability that an F2 plant will be tall is
Gregor Mendel removed the male parts from the flowers of some plants in order to
make controlled crosses the between plants
Many species of plants grown for food are hybrids, what does this mean
they are different from a cross of parents with different alleles
