A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 70% of the offspring resulting from this cross will have red flowers. To test this, 80 seeds from this cross were collected and germinated and 46 plants had red petals.
(a) Is there sufficient evidence at the 0.02 significance level to indicate the proportion of the hybrid plants with red petals differs from 70%? Use the P-value method in your test.
(b) What would a Type I error be in this case?
*Please explain*

A true breeding swan flower plant with smooth petals is crossed with a true breeding swan...
A true breeding swan flower plant with smooth petals is crossed
with a true breeding swan flower plant with constricted petals. The
offspring of this cross all have smooth petals. This indicates
that
1) the offspring do not have a constricted allele in their
genotype
2) smooth petals are dominant and constricted petals are
recessive
3)constricted and smooth petals are not controlled by
alleles
4) the F2 generation will have all smooth petals
5) constricted petals are dominant and smooth...

A true-breeding plant with red flowers was crossed with a
true-breeding plant with white flowers. The F1 progeny all had a
new flower color, pink. The F1 plants were inter-crossed, and
produced 44 red, 135 pink, and 61 white flower plants.
(4 pts.) What is the most likely mode of inheritance being
exhibited in these phenotypes. State your hypothesis and provide
your reasoning, which can also include why other modes of
inheritance are unlikely (process of elimination). Do not assign...

1)A homozygous tomato plant with red fruit and yellow flowers
was crossed with a homozygous tomato plant with golden fruit and
white flowers. The F1 all had red fruit and yellow
flowers. The F1 were testcrossed by crossing them to
homozygous recessive individuals, and the following offspring were
obtained:
Red fruit and yellow flowers41
Red fruit and white flowers7
Golden fruit and yellow flowers8
Golden fruit and white flowers44

A tomato plant with large leaves and round fruits was crossed to a plant with small...
A tomato plant with large leaves and round fruits was crossed to
a plant with small leaves and oblong fruits. The F1 consisted of
plants with large leaves; about half of these plants made round
fruits and the other half made oblong fruits. Two F1 plants (one
with round fruits and one with oblong fruits) were then analyzed
through further crossing. The results were:
Cross
F1 plant #1 with round fruits × parent with round fruits
F1 plant #1 with...

A.
A plant of genotype CCdd is crossed to ccDD. An F1 of that cross is
testcrossed to ccdd. If the genes are unlinked, the percentage of
C_D_ progeny of that cross will be _____%
B. A plant of genotype CCdd is crossed to ccDD. An F1 of that
cross is testcrossed to ccdd. If the genes are so tightly linked
that no recombination occurs between them, the percentage of C_D_
progeny of that cross will be _____%
A pure breeding tall plant with smooth seeds was crossed with a pure breeding short plant...
A pure breeding tall plant with smooth seeds was crossed with a
pure breeding short plant with wrinkled seeds. All the F1 plants
were tall with smooth seeds. Two of these F1 plants were crossed
and four different phenotypes were obtained in the 320 plants
produced. How many tall plants with wrinkled seeds should you
expect to find.

Edward East was a plant geneticist who was greatly interested in
quantitative traits. He is also known for the Mendelian model of
quantitative traits. Explain how his model works if a trait
resulted from 6 genetic loci. Draw graphs in your explanation

In tomatoes, a heterozygous plant with normal fruit and purple
stems is crossed with a recessive plant having fasciated fruit and
green stems. The following distribution of offspring is
observed:
normal fruit, purple stems 38.5% fasciated fruit, green
stems 38.5%
normal fruit, green stems 11.5%
fasciated fruit, purple stems 11.5%
What conclusion can be made regarding the loci for fruit shape and
stem color? HINT determine the RF
What the loci and RF here mean? How to answer this question?
