To review:
In the given question, it is asked to identify characteristics of homologous chromosomes synapsis which can be used to distinguish between two plant species. Plant species A (Diploid) possesses
Introduction:
Prophase-1 is a phase in the process of germ cell division (meiosis) in which duplicated chromosome gets condensed and aligns with their homologous chromosome. This pairing between two homologous partners is followed by a crossing over which results in genetic recombination (exchange of genetic material between pair of homologous chromosomes).
The organism which possesses a pair of homologous chromosomes in its somatic cell is termed as a diploid organism. Similarly, the organism possessing three homologous chromosomes in its somatic cell is termed as a triploid organism.
Explanation of Solution
According to the given information, species-A is diploid and possesses
According to the given information, species-B is triploid and possesses
Diagram-Triploid cell with unpaired chromosome, a pair of homologous chromosome, and trivalent.
In species-A, the possible number of pair of homologous chromosomes is
In species-B, the possible number of triplets could be

Look at the bottom part of As shown in which “mitosis: growth of the body” has produced cells with four different types of chromosomes. The black ones came from the sperm nucleus. The red ones came from the egg nucleus. If one of these nuclei were to undergo meiosis, which chromosomeswould pair during zygotene (which are homologous)— the long black one with the short black one or the long black one with the long red one?arrow_forwardDraw a hypothetical cell’s chromosome configuration undergoing meiosis (show before meiosis, after meiosis I, and then after meiosis II) under each of the following situations: If there is one pair of homologous chromosomes AND there is nondisjunction in meiosis I. If there are two pairs of homologous chromosomes, one labeled ‘A’ and another labeled ‘B’.arrow_forward
- In prophase II of meiosis, each daughter cell is _____. A) diploid, and the chromosomes are each composed of a single chromatid B) diploid, and the chromosomes are each composed of two chromatids C) haploid, and the chromosomes are each composed of a single chromatid D) haploid, and the chromosomes are each composed of two chromatidsarrow_forwardA triploid plant has 18 chromosomes (i.e., 6 chromosomes perset). If we assume a gamete has an equal probability of receivingone or two copies of each of the six types of chromosome, whatare the odds of this plant producing a haploid or a diploid gamete?What are the odds of producing an aneuploid gamete? If theplant is allowed to self-fertilize, what are the odds of producing aeuploid offspring?arrow_forwardMeiosis is characterized by the pairing of homologouschromosomes during prophase I. In many species, an elaboratestructure called the synaptonemal complex forms betweenhomologues. During this pairing, homologues may exchangechromosomal material at sites called chiasmata. In meiosis I, thehomologues separate from each other, reducing the chromosomenumber to the haploid state (thus the reductive division). It isfollowed by a second division without replication, during whichsister chromatids become separated. The result of meiosis I and IIis four haploid cells. If sister chromatids separated at the first division, would meiosis still work?arrow_forward
