RrYyCc x RrYyCc is a trihybrid cross.
what is the probability of having a progeny with all heterozygous genotype?
Genotype- Rr Yy Cc x Rr Yy Cc
(for homozygous genotype probability is 1/4 and for heterozygous it will be 2/4)
Hence, 2/4*2/4*2/4=8/64
i.e. 1/8
1/8 progeny with all heterozygous genotype

A cross is set up: Aa Bbce X AA Bb Cc. What percentage of progeny will be heterozygous at every locus?
BIO 340 Activity # 3: Trihybrid crosses, probability, and pedigrees (PAGE 1 of 2) Name (Last, First): 1. In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted pod shape (f). If two heterozygous plants (PpFf) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? х — What are the gametes for each parent?...
I'm having trouble understanding this problem. The most frequent
F2 progeny seem to have had crossover to me because the parents are
Aa Bb x aa bb but the progeny are Aa bb and aa Bb. I thought
parental progeny would have the same genotype as the parents. Can
you please explain how the most frequent progeny don't have
crossover? Thank you
In a dihybrid test cross the genotype of the F1 individual is Aa Bb and the tester genotype...
In a trihybrid cross between individuals who are heterozygous for all three traits, the expected proportion of offspring showing dominance for one trait and recessive for the other two is 1/16 1/64 27/64 9/16 9/64
The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
2)...
When considering a single character, the progeny of a test cross have a 1:1 ratio of dominant to recessive phenotypes. 1) the phenotype of the non-tester parent is a) recessive b) dominant c) homozygous d) heterozygous e) not enough information to solve this problem 2) The genotype of the non-tester parent is a) homozygous dominant b) heterozygous c) homozygous recessive d) hemizygous e) not enough information to solve this problem
Name: 5. A heterozygous trihybrid com plant is test crossed and the following progeny are produced. The mutant traits-booster (b), silkless (s), liguleless (1) - are recessive to their wild-type (+) alternatives. (Hint: The wild-type alternatives (+) for each of the three mutant traits can be named B, S, and L, respectively.) (6 points) Note: This is a three point cross. Show all your work to get full credit. You will get partial credit for any work that is correct...
You perform a trihybrid cross: You cross true-breeding purple-flowered, round, yellow peas (PPRRYY) with true-breeding white-flowered, wrinkled, green peas (pprryy). You then cross the resulting F1 offspring together to generate an F2 generation. What is the probability of an F2 plant having white flowers and producing round, yellow peas?
In a trihybrid test cross of ++++++ female x blblvgvgbrbr males, would the F1 flies that are crossed both be from the F1 yeilded from the parentals? Or would new ++++++ females be brought in?
