Plant species A (n=7) is crossed with a species B (n=10) and produces a fertile hybrid that will be
a. triploid
b. autotetraploid
c. allotetraploid
d. trisomic
e. monosomic
How many chromosomes will the hybrid have
a 7
b 10
c 14
d. 17
e. 34
Homework Answers
Q1)
c. allotetraploid
The plant will be fertile only if the two sets of chromosomes have homologous partners during meiosis. This will only occur if the two sets of chromosomes from A and B become doubled in the Hybrid, making the Hybrid plant Allo(from different parents) - tetraploid.
Q2)
e. 34
The chromosomes from Set A will double to 14 (2A = 14) and the chromosomes from Set B will double to 20 (2B = 20). Therefore, the organism will have 34 chromosomes.

Timoracam X (A genome) Ticarsi (B genome) sterile hybrid 1. turgidum (Emmer wheat) fertile hybrid 4. During the evolution of wheat, two wild diploid species were crossed to form Emmer wheat (Triticum turgidum). One diploid (2n = 14) T. monococcum had the A set of chromosomes and the other diploid (2n = 14) T. searsii had the B set. The initial cross produced a sterile hybrid, from which a fully fertile hybrid eventually arose, as shown below: Imam X genome)...

A plant species X with n=5 chromosomes was crossed with a related species Y with n = 7 chromosomes. The F1 hybrids produced only a few pollen grains, which were used to fertilize the ovules of related species Z with n=7 chromosomes. A few plants were produced from this cross, and all had 19 chromosomes. The F1 hybrids (with 19 chromosomes) were mated with related species W with n=11 chromosomes. A few plants were produced from the cross and all...

QUESTION 5 You cross want to create a new hybrid plant. You cross Plant 1 (2n=10) with Plant 2 (2n=14) and generate a generation of hybrid plants. Most of the hybrid plants are infertile, however, you do find a hybrid plant that is fertile. You reason that this plant must have undergone a non-disjunction event that now rendered it fertile. If your reasoning is correct, how many chromosomes does this fertile hybrid plant have? O a. 24 Ob. 12 O...

A true breeding plant that produces white flowers is crossed with a true breeding plant that produces red flowers. The resulting F1 are all plants with pink flowers. One of the pink-flowered plant is crossed to a true breeding white plant and 16 plants are produced. How many plants do you expect to see from each phenotype?

Question 2 (11 points) In the plant genus Triticum there are many different polyploid species, as well as diploid species. Crosses were made between three different species, and hybrids were obtained. The meiotic pairing was observed in each hybrid, and this is recorded in the following table. (Hint#1: A bivalent is two homologous chromosomes paired at meiosis, and a univalent is an unpaired homolog at meiosis. HINT #2 : For this question, review your knowledge of chromosome inheritance and pairing...
