You are breeding two poly ploidy species of wheat. you cross the two different species (parent 1 x parent 2) and obtain F1 hybrids. The following meiotic pairing is observed: F1 hybrid= 12 bivalents + 12 univalents
A) how many chromosomes are there in a non-dividing somatic cell of an F1 plant (what is the organisms ploidy?)
B) how many chromosomes are there in a non-dividing somatic cell of each parent (what is the organisms ploidy?)
C) for each parent identify whether the plant is diploid, autoploidy or alloployploid.

Homework Answers
A. The non-dividing F1 plant has 12 bivalents+12 univalents. It has a total of 36 chromosomes.
B. There are 12 chromosomes each in the non-dividing somatic cell of the parent 2, whereas the number is 24 for parent 1.
C. Parent 1 is autotetraploid whereas the parent 2 is diploid.

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...

You have two families of true-breeding diploid Zea mays(maize, corn) plants. Late flowering, with tall stalks Early flowering, with short stalks A cross between these two plants yields F1 hybrids that are late flowering, with tall stalks. Given this information, which alleles are dominant? Explain your reasoning. Using the letters F or f for flowering and T or t for stalk height, indicate the genotypes of the two plants. Plant 1 ______________ Plant 2 ___________________ What is the genotype of the...

You are studying two different unrelated organisms. In the first, you cross a true-breeding colorless individual with a true-breeding red individual. All F1 offspring are red. When you cross two F1 individuals, you get 70 reds and 58 colorless. The reciprocal cross gives similar results. In the second organism, you cross a true-breeding colorless with a true-breeding blue. All F1 offspring are colorless. When you cross the F1 offspring you get 23 blue individuals and 105 colorless individuals. Again the...

20. A "zony" is a cross between a female pony (2n=64) and a male zebra (2n = 44). Zonies are and have a normal lifespan but the different number of chromosomes between the two parent species means they are unable to produce offspring of their own. Zonies are an example of: hybrid inviability hybrid sterility hybrid breakdown autopolyploidy meiotic error 21. Which of the following would best be described as a case of speciation in sympatry? a.

Could someone check my answers, please? 1. Suppose that a species of fish has split into two populations in a lake: one on the eastern side and one on the western side. How could you determine whether the two populations constitute different species? A. Examine the populations for morphological, color, or other physical differences. B. Examine the populations for different genetic markers and allele frequencies. C. Attempt to breed members from the two populations in captivity. D. Introduce members from...
